Procedure

A solution of 2.3 g (0.1 mol) of sodium in 150 ml of methanol is mixed with 16.8 g (0.1 mol) of methyl thiosalicylate and then a solution of 24.4 g (0.1 mol) of N,N'-diphenyl-2-chloroacetamidine in 250 ml of methanol is added. After heating under reflux for 1 hour, the mixture is poured into ice water and the precipitate filtered and recrystallized from an ethanol/water solution to yield 26.5 g of yellow needles having an m.p. of 152-153° C.
