Reaction Steps

A solution of ethyl 2,4-dichloropyrimidine-5-carboxylate (prepared as described in WO2009/131687, 0.29 g, 1.31 mmol), (S)-1-(5-fluoropyridin-2-yl)ethanamine hydrochloride (prepared as described in WO2006/123113, 0.28 g, 1.59 mmol) and diisopropylethylamine (0.69 mL, 3.96 mmol) in acetonitrile (3 mL) was stirred overnight at ambient temperature. Water was then added and the reaction mixture was extracted with diethyl ether. The organic phase was washed with water and brine, dried (MgSO4), filtered and the solvents evaporated under reduced pressure to yield the title compound (0.49 g, 85%) as an oil.
