Benzene → HCID 12783508, compound

Participants

Reaction Steps

A mixture of 2.6 g. of 2-ethyltetrahydro-2H-1,3-thiazine, 3.4 g. of 3-chlorophenyl isothiocyanate, and 30 ml. of benzene was stirred, after an initial exotherm, at ambient temperature for about 64 hours. To the reaction mixture was added about 10 ml. of hexane, which caused white crystals to form. The mixture was cooled and filtered, and the solid was washed with hexane. The solid was recrystallized from about 500 ml. of 10:1 hexane:carbon tetrachloride to give N-(3-chlorophenyl)-2-ethyltetrahydro2H-1,3-thiazine-3-carbothioamide, m.p. 69°-73°. The following elemental microanalysis was obtained:
