Paragraph 0061, (2016/11/14)

PROBLEM TO BE SOLVED: To provide a method for manufacturing voriconazole, which is a therapeutic agent for severe or intractable deep mycosis such as aspergillosis, allowing easy manufacture without the need for the optical resolution. SOLUTION: A method for manufacturing voriconazole includes: obtaining a compound represented by the general formula (3) by using catalytic asymmetric cyanoacylation reaction; and reacting the compound with 1,2,4-triazole to convert it into voriconazole. [In the general formula (3), X is any of the divalent groups represented by the specified structural formulas.] COPYRIGHT: (C)2015,JPOandINPIT
