Document Type and Number:
WIPO Patent Application WO/2024/071178
Kind Code:
A1
Abstract:
Provided is an industrially useful method for producing an alkylsilyloxy-substituted benzylamine compound, in which impurities are easily removed and the method does not involve an alkylsilyloxy-substituted benzyl compound that is an intermediate compound that is unstable to acids. The present invention relates to a method for producing a ketimine compound represented by general formula (3) (in the formula, R1b to R5b and RB are as defined below), the method being characterized by reacting a silazane compound with a benzoyl compound represented by general formula (2) (in the formula, 1 to 5 of R1b to R5b are hydroxyalkyloxy groups having 1-16 carbon atoms, with the remainder being hydrogen atoms, halogen atoms, or the like; and RB is a hydrogen atom, a hydroxyl group, an alkoxy group having 1-6 carbon atoms, or the like).
