To a solution of 3-chloro-4-methoxy acetophenone (3.0 g, 16.30 mmol) in DMF (15 mL) was added 60% NaH [0.717 g (0.430 g, 17.93 mmol)] at 0° C. under a nitrogen atmosphere. The mixture was stirred for 30 min and a solution of nicotinic acid ethyl ester (2.95 g, 19.56 mmol) in DMF (10 mL) was added slowly to it. The mixture was stirred at temperature in the range of 20-40° C. for 12 hour. It was then poured into ice-cold water (100 mL) and stirred for 15 minutes. The solid was filtered and dried to give the desired compound.
