To a solution of 2-(3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)azetidin-3-yl)acetonitrile hydrochloride (Example 62; 30 mg, 0.069 mmol) in acetonitrile (690 μL, 0.069 mmol) was added K2CO3 (38 mg, 0.28 mmol) and 2-bromopyrimidine (12 mg, 0.076 mmol). The reaction mixture was heated to 45° C. for 3 days. After diluting in EtOAc, the mixture was washed with water and brine. The organic layer was dried with MgSO4, filtered and concentrated in vacuo to a clear colorless oil. The oil was purified by reverse phase HPLC using 0-100% acetonitrile/water gradient to afford 2-(3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)-1-(pyrimidin-2-yl)azetidin-3-yl)acetonitrile (6.1 mg, 20% yield) as a white solid. MS (apci) m/z=438.2 (M+H).
