Procedure

7-(1-Methyl-1H-pyrazol-4-yl)-5-(1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidine (Preparation K-1; 0.050 g, 0.189 mmol), 2-(spiro[3.3]heptan-2-ylidene)acetonitrile (0.050 g, 0.377 mmol) and 2,3,4,6,7,8,9,10-octahydropyrimido[1,2-a]azepine (0.014 mL, 0.094 mmol) were suspended in MeCN (3 mL) and stirred at ambient temperature overnight. The reaction mixture was concentrated under reduced pressure and the crude material purified by flash column chromatography, eluting with 1-4% (9:1 MeOH:NH4OH)/DCM to provide 2-(2-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)spiro[3.3]heptan-2-yl)acetonitrile (0.032 g, 0.080 mmol, 42% yield). MS (apci) m/z=399.2 (M+H).
