Participants

Reaction Steps

2-(1-sopropylpiperid-4-ylmethyl)-6-chloro-1,2-benzisothiazolin-3-one is obtained analogously to Example 33 by reacting 3-chloro-6-chlorocarbonylphenylsulfenyl chloride and 1-isopropyl-4-aminomethylpiperidine [boiling point 15 :95°-97° C.; obtained from 4-acetylaminomethylpiperidine and isopropyl chloride analogously to Singh et al., J. Med. Chem. 12, 949 (1969) and Werbel et al., supra]. After recrystallization in acetone, yellow crystals of melting point 134°-135° C. are obtained; yield: 37% of theory.
