2-Pentanamine → 2-(1-Methylbutyl)benzisothiazolin-3-one

Participants

Reaction Steps

2-Chlorosulphenylbenzoyl chloride (6 parts, 0.029M) dissolved in diethylether (30 ml) was added dropwise at 0 to 3° C. to a stirred solution of 1-methylbutylamine (7.36 parts, 0.84M ex Aldrich) in diethylether (30 ml). The reactants were stirred for 16 hours whilst allowing the temperature to rise to about 20° C. The ether solution was then screened, washed with water and dried over magnesium sulphate. After evaporation of the ether, the product was obtained as a pale yellow gum (5.5 parts, 86% theory) which gradually solidified on standing. This was recrystallised from hexane. mp=52-54° C.
