The Structure of “7-Dehydrocholestene Isomer”¹

Abstract

Structure of "7-Dehydrocholestene Isomer" 107 with 75 ml. of water and heated to 90°. The solution was chilled and the solid recrystallized from water. The yield of a-chloro-a-£-tolylsulfonylacetamide (I) was 1 g. (4.4%), m. p. 162-165°. Repeated recrystallizations from water and alcohol gave «-^-tolylsulfonylacetamide.Reaction of Sodium «-Butyl Mercaptide with Dichloroacetamide.-To 10.7 ml. (9 g., 0.10 mole) of «-butyl mercaptan was added a sodium ethoxide solution prepared by dissolving 2.3 g. (0.10 gram atom) of sodium in 60 ml. of absolute alcohol. This was added dropwise, at room temperature, to a well stirred solution of 20 g. (0.15 mole) of dichloroacetamide in 150 ml. of absolute alcohol. After
