Reaction Conditions

Reaction Steps

1-(5-fluoro-2-methylpyrimidin-4-yl)-4,4′-bipiperidine (16 mg, 0.058 mmol) and cesium carbonate (57 mg, 0.17 mmol) were stirred in NMP (0.6 ml) and 2-chloro-5-fluoropyrimidine (0.014 mL, 0.116 mmol) was added. The mixture was heated at 70° C. for 1 h. The reaction was cooled down to r.t. and diluted with ethyl acetate (5 mL) and was washed with water 2 mL (×1) and brine 2 mL (×1). The organic phase was dried over magnesium sulfate, filtered, and concentrated on rotavapor. The crude material was purified by preparative TLC with 30% acetone: hexane to yield the titled compound. LC-MS: 375.06 (M+H). Examples reported in Table 14 are prepared in accordance with Procedure 14.1.
