Reaction Steps

Combine 2-(4-(3,4-difluorophenyl)-2-(piperidin-4-yl)-1H-imidazol-1-yl-N,N-dimethyl ethanamine (0.35 g; 0.0010 mol; 1.0 equiv), 4-chloro-5-ethyl-5,7-dihydro-pyrrolo[2,3-d]pyrimidin-6-one (0.23 g; 0.0011 mol; 1.1 equiv), DIPEA (0.72 mL; 0.0041 mol; 4.0 equiv) in IPA (10 mL) and stir at 90° C. for 16 h. Quench the reaction with demineralized water and extract with EA. Evaporate the organic layer, purify over a silica gel column with 0-10% MeOH/DCM to give the title compound (0.13 g; 24.13%). MS (ES+): m/z=496 (M+H).
