Reaction Steps

To 4-aminothiophenol (1.70 g, 13.6 mmol) and Cs2CO3 (8.90 g, 27.2 mmol) was added DMSO (18 mL). The mixture was stirred for 5 minutes at 100° C. before 4-(2-chloropyridin-3-yl)-N-methylpyrimidin-2-amine (3.00 g, 13.6 mmol) was added. The resulting mixture was stirred for 16 hours at 130° C., then diluted with water and the resulting solid filtered. After washing the solid with water and Et2O it was dried under vacuum to yield the desired product as a tan solid. MS m/z=310 [M+1]+. Calc'd for C16H15N3S: 309.40.
