To 2-chloro-4-(2-chloro-pyridin-3-yl)-5-fluoro-pyrimidine (178 mg, 0.73 mmol) and methylamine hydrochloride (74 mg, 1.1 mmol) was added K2CO3 (202 mg, 1.46 mmol) and DMSO (1.5 mL). The mixture was heated overnight in a sealed tube at 55° C. The mixture was cooled to RT, diluted with EtOAc and water, then neutralized with TFA (pH˜6-7). The organic layer was washed several times with water, dried over Na2SO4, filtered and concentrated to yield [4-(2-chloro-pyridin-3-yl)-5-fluoro-pyrimidin-2-yl]-methyl-amine. MS m/z=239 [M+1]+. Calc'd for C10H8ClFN4: 238.65.
