Reaction Steps

2-Ethoxybenzamidine (from sodium, 0.08 g, in ethanol, 10 ml, and 2-ethoxybenzamidine hydrochloride, 0.70 g) was dissolved in acetonitrile (10 ml) and the resulting cooled (2° C.) solution was added to a cooled (2° C.) suspension of ethyl 4-chloro-2-methylthio-5-pyrimidine carboxylate (0.81 g) in acetonitrile (10 ml). The reaction mixture was stirred at 2° C. for one hour. Triethylamine (0.35 g) was added and the reaction mixture was stirred at ambient temperature for 21 hours to yield a white precipitate, 0.22 g, which was collected by filtration. The filtrate was reduced in volume under reduced pressure to yield a second crop of solid, 0.41 g. The products were combined and recrystallised from ethanol to yield the title compound, 0.30 g, m.p. 224.5°-225.5° C.
