Procedure
20.8 g (0.105 mol) of cyclohexylaminosulfonyl chloride in 60 ml of tetrahydrofuran were added dropwise, over a period of 2 hours, at -50° C., to a solution of 16.7 g (0.1 mol) of morpholinocyclohex-1-ene and 10.6 g (0.105 mol) of triethylamine in 150 ml of tetrahydrofuran, the mixture was brought to 20° C. over a period of 4 hours and filtered, the filtrate was evaporated to dryness in vacuo and the residue was chromatographed on 80 g of silica gel with methylene chloride. After crystallization from diisopropyl ether, the main fraction yielded 14.9 g (57.4%) of colorless crystals of melting point 105°-109° C.
