Reaction solution was allowed to cool to room temperature, and the organic layer was removed under reduced pressure. Ethyl acetate was added, the layers were partitioned and the aqueous layer was extracted with ethyl acetate (250 mL). The organic layers were combined, washed with water and brine, dried over magnesium sulfate, filtered and evaporated under reduced pressure. The residue was purified by flash chromatography on silica using 10% methanol in dichloromethane, then 20% methanol in dichloromethane as eluent to give 0.241 g (51%) of 4-chloro-5-(4-phenoxyphenyl)-7-[1-(1-methyl-4-piperidinyl)-4-piperidinyl]-7H-pyrrolo[2,3-d]pyrimidine.
