- Antibodies to quetiapine haptens and use thereof
-
Disclosed is an antibody which binds to quetiapine, which can be used to detect quetiapine in a sample such as in a competitive immunoassay method. The antibody can be used in a lateral flow assay device for point-of-care detection of quetiapine, including multiplex detection of aripiprazole, olanzapine, quetiapine, and risperidone in a single lateral flow assay device.

- Process for preparing dibenzothiazepine compounds
-
A dibenzothiazepine compound is suitably prepared by subjecting a 2-amino-2′-carboxy-diphenylsulfide compound to dehydration-condensation reaction in the presence of an acidic catalyst; the 2-amino-2′-carboxy-diphenylsulfide compound is suitably prepared by reducing a 2-nitro-2′-carboxy-diphenylsulfide compound in a lower aliphatic ester solvent; and the 2-nitro-2′-carboxy-diphenylsulfide compound is suitably prepared by reacting a nitrobenzene compound with a thiosalicylic acid compound in a mixture of a lower aliphatic alcohol and water.

- PROCESS FOR PRODUCING 11-[4-[2-(2-HYDROXYETHOXY)ETHYL]-1-PIPERAZINYL]DIBENZO[b,f][1,4]THIAZEPINE AND A PHARMACEUTICALLY ACCEPTABLE SALT THEREOF
-
A process for producing 11-[4-[2-(2-hydroxyethoxy)ethyl]-l-piperazinyl]dibenzo [b,f][1,4]thiazepine [I] and a pharmaceutically suitable acid addition salt is disclosed. Accordingly, thiosalicylic acid [XVI] is reacted with o-halonitrobenzene [XVII] using a phase transfer catalyst to obtain 2-nitro-2'-carboxydiphenylsulphide [XI]. It is hydrogenated in the presence of a noble metal catalyst to obtain 2-amino-2' carboxydiphenyl sulphide [X]. The 2-amino-2'-carboxydiphenylsulphide [X] is reacted with halide or oxyhalide of the phosphorous to obtain in situ iminohalide [VI], which further reacts as such with 1-hydroxyethoxyethylpiperazine or condenses with piperazine to obtain 11-piperazinyldi.benzo[b,f][1,4]thiazepine [XIX] which further reacts with 2- chloroethoxyethanol or reacts with 1-(2-hydroxyethyl)piperazine to give 11-[4-(2-hydroxyethyl)piperazine-1-yl]dibenzo[b,f][ 1,4]thiazepine [XXXI] which further converts to an intermediate 11-[4-(2-substitutedethyl)piperazin-1- yl)dibenzo[b,f][1,4]thiazepine wherein the substituent at the 2-position is selected from mesyloxy or tosyloxy or halo group [XXXII] followed by reaction with ethylene glycol to give quetiapine [1].

- PROCESS FOR PRODUCING DIBENZOTHIAZEPINE DERIVATIVES
-
A process for preparing a dibenzothiazepine derivative such as dibenzo[b,f] [1,4]thiazepin-11-one employable as a starting material for the preparation of 11-[4-(2-(2-hydroxyethoxy)ethyl)]-1-piperadinyldiberizothiazepine derivative which is known to be effective as an antipsychotic pharmaceutical, has the steps of reacting a nitrobenzene derivative with a thiosalicylic acid derivative, reducing the obtained 2-nitro-2'-carboxy-diphenylsulfide derivative, and subjecting the obtained 2-amino-2'-carboxy-diphenylsulfide derivative to dehydration-condensation reaction.

- NOVEL REACTIONS OF SPIROSULFURANE PRECURSOR SULFIDES AND SULFOXIDES
-
The SIV spirosulfurane 19 and the lactam-sulfoxides 21, 22 and 23 with seven-, eight- and nine-membered rings have been prepared by oxidation and dehydration of trifluoroacetylaminoarylcarboxyphenyl sulfides and sulfoxides, respectively.A mechanism is proposed for the formations of lactam-sulfoxides.The preparation of the starting sulfides and sulfoxides is also described. Key words: Diaryl sulfides; diaryl sulfoxides; spirosulfurane; lactams; carboxyl activation; lactam-sulfoxide formation.
