Procedure

A solution of 2.36 ml of triethylamine in 15 ml of chloroform was treated dropwise at -10° C. with a solution of 2.18 g of p-[trans-4-(5-hexenyl)cyclohexyl]aniline in 20 ml of chloroform. After 5 minutes the mixture was treated with a solution of 690 μl of thiophosgene in 10 ml of chloroform, warmed to room temperature and stirred for 2 hours. Thereafter, the reaction mixture was partitioned between water and chloroform. The organic phase was dried over magnesium sulphate and concentrated. Chromatographic separation on 140 g of silica gel using ethyl acetate/petroleum ether (vol. 5:95) and subsequent crystallization from 80 ml of methanol and low temperature filtration gave 1.24 g of p-[trans-4-(5-hexenyl)cyclohexyl]phenylisothiocyanate (purity 100%) as a milky liquid of m.p. (C-N) 15.2° C. and cl.p. (N-I) 46.1° C.
