7-(1-Methyl-1H-pyrazol-4-yl)-5-(1H-pyrazol-3-yl)imidazo[1,2-c]pyrimidine hydrochloride (Example 129, Step C, 50.2 mg, 0.148 mmol) and 3-cyclopropylacrylonitrile (Preparation B; 69.1 mg, 0.742 mmol) were suspended in acetonitrile (742 μL, 0.148 mmol). DBU (88.8 μL, 0.594 mmol) was added to the reaction mixture and heated at 45° C. for 15 hours. The reaction mixture was purified by reverse phase HPLC using a 0-100% acetonitrile/water gradient. The resultant solid was diluted in Et2O, sonicated, filtered and washed with Et2O to afford the title compound as a light yellow solid (9.3 mg, 17% yield). MS (apci) m/z=359.2 (M+H).
