실험 절차

7-Chloro-5-(1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidine (Preparation M, Step A; 0.380 g, 1.73 mmol), 2-(spiro[3.3]heptan-2-ylidene)acetonitrile (Example 160, Steps A-C, 0.461 g, 3.46 mmol) and DBU (0.130 mL, 0.865 mmol) were suspended in MeCN (10 mL) and stirred at ambient temperature overnight. The reaction mixture was partitioned between saturated aqueous NH4Cl and EtOAc. The organic layer was washed with brine, dried (MgSO4), filtered concentrated under reduced pressure to afford the crude material, which was purified by flash column chromatography, eluting with 2-3% (9:1 MeOH:NH4OH)/DCM to provide 2-(2-(4-(7-chloroimidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)spiro[3.3]heptan-2-yl)acetonitrile (0.493 g, 1.40 mmol, 81% yield). MS (apci) m/z=353.1 (M+H).
