Reaction Conditions

Reaction Steps

To a clear solution of 4-Methoxy-indan-5-carbaldehyde (11.5 gm, 0.065 mole) in Dichloromethane (100 ml), Sulphamic acid (19.0 gm, 0.196 mole) was added at 25-28°. A solution of Sodium chlorite (15.28 gm, 0.169 mole) in water (50 ml) was added at 5-10° C. The reaction mixture was stirred for 5 hours at 25-28° C. Finally the reaction mixture was poured into water (200 ml) and extracted with Dichloromethane (2×200 ml). The organic layer was dried over Sodium sulphate, distilled under vacuum to give 12.0 gm of desired product as a viscous oil.
