Procedure
4-Octadecyloxycarbonylbenzyl bromide (4.7 g, Step 2) and 2-methylmercaptobenzothiazole (2.5 g) were heated together for 35 minutes/190°-195° C. The mixture was cooled and triturated with ligroin to produce a solid which was recrystallized from pyridine/methanol to form the product; yield 4.5 g (81%), m.p. 105°-107° C.
