Procedure

A mixture of 89.9 g of N-t-butyl-2-(2-propenylthio)benzenesulfonamide and quinoline (90 ml) were heated at 220° C. for 2 hours under an inert atmosphere. The mixture was cooled, was poured into ice-water (500 ml) and was extracted with several portions of a 1:1 mixture of chlorobutane and tetrahydrofuran. The combined extracts were washed with 6N hydrochloric acid and brine. The organic mixture was dried over magnesium sulfate and was concentrated. The residue was distilled in a kugelrohr apparatus at 170°-200° C. (1 torr), giving after trituration with chlorobutane and hexane a yellow solid. Chromatography of the mixture on silica gel eluting with 20% ethyl acetate in hexane afforded after recrystallization from hexanechlorobutane the title compound as a white solid, m.p. 97°-98° C.
