A mixture of 4-chloro-3-(6-cyano-4-methyl-pyridin-3-yl)-N-(2-hydroxy-phenyl)-N-methyl-benzamide 8-1 (50 mg, 0.13 mmol), 4-bromopropanol (18 μL, 0.2 mmol) and K2CO3 (55 mg, 0.40 mmol) in DMF (0.4 mL) was stirred at room temperature for 14 hrs. Ethyl acetate was added and the combined organic layers were washed with water, dried over Na2SO4, then purified by silica gel column chromatography eluting with ethyl acetate/hexane (2/3) up to 100% EtOAc to yield 4-chloro-3-(6-cyano-4-methyl-pyridin-3-yl)-N-[2-(3-hydroxy-propoxy)-phenyl]-N-methyl-benzamide (30 mg).
