Reaction Steps
A solution of indane-2,2-dicarboxylic acid (17 g, Baeyer and Perkin, Ber. 1884, 17, 122) in NMP (200 ml) was heated to 150° C. for 1 hour. After cooling to 20° C. the solution was poured in water (300 ml) and concentrated hydrochloric acid was added to pH=1. Conventional work up with ether gave the title product (4.7 g). Mp 132-33° C. (from ether).
