After completion of the reaction, the reaction mixture was washed with water, followed by 10% sodium bicarbonate solution and then distilled off the solvent from the reaction mixture under reduced pressure. Dichloro methane (5 ml) was added to the obtained residue and stirred for 15 minutes to get clear solution. The resultant reaction mixture was added to n-heptane (20 ml) over a period of 15 minutes at 25-35 degrees C and cooled to 0-5 degrees C. The reaction mixture was stirred for 60 minutes at 0-5 degrees C. After work up (S)-10-acetoxy-10,11-dihydro-5H-dibenz(b,f)azepine-5-carboxamide (yield: 1.5 g) was obtained.
