Procedure

9.5 ml Of 28% methanolic solution of sodium methoxide were added to a solution of 6.0 g of 2-mercapto-6-methyl-3-phenyl-4(3H)-quinazolinone and 4.0 g of 2-chloromethylpyridine hydrochloride in methanol, the mixture was stirred at room temperature for 2 hours and allowed to stand overnight. Crystals precipitated were collected by filtration and recrystallized from ethyl acetate to give 4.2 g (52.2%) of the title compound.
