Reaction Conditions

Reaction Steps

A 10 L pressure reactor was charged with dry Pd/C (30 gm), 4-(2′-phthalimidoethyl)-3-chloro-1,3-dihydro-2H-indol-2-one (300 gm, 0.882 mol), triethylamine (133 gm, 0.952 mol) and dimethylformamide (6 L). The reaction mixture was hydrogenated at 30-50° C. and 70-75 psi for 2 hours. The catalyst was filtered at 50° C. and filtrate was concentrated in vacuum. Water (1.5 L) was added to residue and slurry was stirred for 30 minutes at 30° C. The solids were filtered at suction and washed with water, and dried in oven at 60-70° C. to give title compound as yellow solid (225 gm, 83.3%).
