Reaction Steps
A solution of 6-hydroxy-2-(2-naphthylmethylthio)-pyrimidine-4-carboxylic acid ethyl ester (2.32 g, 6.81 mmol) and 2-picoline (0.7 ml) in POCl3 (7 ml) were stirred at rt for 3 hrs, then poured onto ice. The solid was collected by filtration then heated briefly with NH4OH for 15 min. The solid was collected and recrystallized from methanol to yield 1.72 g (70%) of 6-chloro-2-(2-naphthylmethylthio)-pyrimidine-4-carboxylic acid ethyl ester, mp 95-96° C.
