Reaction Steps

To a clear solution of 4-Methoxy-indan-5-carboxylic acid (12.0 gm, 0.0625 mole) in Tetrahydrofuran (60 ml), Carbonyl-diimidazole (13.24 gm, 0.0812 mole) was added at 25-28° C. The reaction mixture was heated to 65-70° C. and stirred for 2 hours to the reaction mixture, a solution of Pyrrolidine (5.74 ml, 0.0687 mole) in Tetrahydrofuran (20 ml) was added at 10-15° C. The reaction mixture was poured into water (200 ml) and extracted with Ethylacetate (2×100 ml). The organic layer was dried over Sodium sulphate, distilled under vacuum and purified by column chromatography using Ethyl acetate:Hexane (20:80) as mobile phase. The fractions were distilled under vacuum to give 6.0 gm of desired product as a viscous oil.
