Dissolve 2-(4-chloro-phenyl)-5-(1H-indol-5-yl)-6,7-dihydro-5H-thiazolo[5,4-c]pyridin-4-one (49 mg, 0.13 mmol) in DMF (1 mL) and add sodium hydride (17 mg, 0.42 mmol). Stir the mixture at room temperature for 30 min then add 2-bromomethyl-pyridine hydrobromide (35 mg, 0.14 mmol). Stir the mixture at room temperature for 5 h, then dilute with EtOAc (30 mL) and wash with saturated NaHCO3 (10 mL). Dry, filter and concentrate the organic solution. Purify the crude material by flash chromatography, using a linear gradient of 20% to 80% EtOAc/hexanes as eluent, to give the title compound (32 mg, 52%).
