A convenient method has been developed for the synthesis of imatinib and two of its intermediates. N-(2-Methyl-5-nitrophenyl)-4-(3-pyridyl)-2-pyrimidin amine, obtained from 2-(methylsulfonyl)-4-(3-pyridyl)pyrimidine via nucleophilic substitution, was reduced by N2H4H2O/FeCl 3·6H2O/C in 92% yield. The resulting amine was condensed with 4-[(4-methylpiperazin-1-yl)methyl]benzoic acid dihydrochloride, which was prepared from 4-(chloromethyl)benzonitrile via substitution and hydrolysis reactions, to provide the final product imatinib in good yield and high purity.

A general aminoalkylation of aryl halides was developed, overcoming intolerance of free amines in nickel-mediated C-C coupling. This transformation features broad functional group tolerance and high efficiency. Taking advantage of the fast desilylation of α-silylamines upon single-electron transfer (SET) facilitated by carbonate, α-amino radicals are generated regioselectively, which then engage in nickel-mediated C-C coupling. The reaction displays high chemoselectivity for C-C over C-N bond formation. Highly functionalized pharmacophores and peptides are also amenable.

Mycobacterium abscessus (Mab) is a rapidly growing species of multidrug-resistant nontuberculous mycobacteria that has emerged as a growing threat to individuals with cystic fibrosis and other pre-existing chronic lung diseases. Mab pulmonary infections are difficult, or sometimes impossible, to treat and result in accelerated lung function decline and premature death. There is therefore an urgent need to develop novel antibiotics with improved efficacy. tRNA (m1G37) methyltransferase (TrmD) is a promising target for novel antibiotics. It is essential in Mab and other mycobacteria, improving reading frame maintenance on the ribosome to prevent frameshift errors. In this work, a fragment-based approach was employed with the merging of two fragments bound to the active site, followed by structure-guided elaboration to design potent nanomolar inhibitors against Mab TrmD. Several of these compounds exhibit promising activity against mycobacterial species, including Mycobacterium tuberculosis and Mycobacterium leprae in addition to Mab, supporting the use of TrmD as a target for the development of antimycobacterial compounds.
