Reaction Steps

Heat a solution of 2-chloro-6-trifluoromethyl-3-H-imidazo[4,5-b]pyridine (0.1 g, 0.45 mmol) and spiro[isobenzofuran-1,4′-piperidin]-3-one (0.2 g, 0.90 mmol) in dry NMP (5 mL) at 100° C. for 10 hours. Pour the cooled mixture into water (20 mL) and extract twice with EtOAc (20 mL). Wash the combined extracts with brine (20 mL), dry, and evaporate in vacuo. Purify by preparative TLC (4% MeOH-CH2Cl2) to obtain 1′-(6-trifluoromethyl-3-H-imidazo[4,5-b]pyridine-2-yl)-spiro[isobenzofuran-1,4′-piperidin]-3-one as a yellow solid.
