A solution of (±) trans-1-chloro-2-tert-butoxycarbonylaminoindane (10.0 g, 0.037 mol) in chloroform (200 ml) was heated under reflux in an argon atmosphere for 23 h. The mixture was concentrated in vacuo to give a brown solid. Trituration with diethyl ether afforded the title compound as a beige solid (6.0 g, 92%) m.p. 205°-206° C. which was used without further purification.
