Document Type and Number:
WIPO Patent Application WO/2013/172412
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a method for producing, at a high yield, a sulfonyl amide compound containing a fluorinated aliphatic group, the method comprising: a first step of adding a ketone compound (a1) having 5 to 10 carbon atoms and a diamine compound (a2) to an organic solvent (a3) such that the ratio of carbonyl groups (a1-1) in the ketone compound (a1) and amino groups (a2-1) in the diamine compound (a2) is in a range of 0.3 to 0.95 in [(a1-1)/(a2-1)] molar ratio, and reacting the ketone compound (a1) and the diamine compound (a2) in the organic solvent (a3) to obtain a compound (A) that contains an amino group and a ketimine group; a second step of reacting the compound (A) with a sulfonyl chloride compound (B) containing a fluorinated aliphatic group to obtain a fluorinated aliphatic group-containing compound (C) that has a ketimine group; and a third step of hydrolyzing the ketimine group in the compound (C) to generate an amino group in the compound (C).
