Procedure

A mixture of formamidine acetate (1508 mg, 14.48 mmol), ethyl 4-(4-chlorophenylthio)-3-oxobutanoate Part A (790 mg, 2.90 mmol) and phenol (8178 mg, 87 mmol) was stirred at 140° C. for 18 hours. After the reaction cooled to RT, the mixture was diluted with saturated NaHCO3 (65 mL) and extracted with EtOAc (80 mL). The EtOAc layer was dried over Na2SO4 and concentrated. The crude product was purified by flash chromatography (silica gel/hexane-EtOAc 100:0 to 0:100 gradient, using LC-MS to identify fractions containing the desired product) to afford 6-((4-chlorophenylthio)-methyl)pyrimidin-4(3H)-one 10B (169 mg, 22% yield). 1H NMR (400 MHz, CD3OD) δ ppm 7.97 (1H, s), 7.07-7.25 (4H, m), 6.06 (1H, s), 3.80 (2H, s).
