Reaction Steps

The title compound was prepared from 2-chlorobenzimidazole and racemic 1-amino-5-bromoindane (prepared by Procedure B from 5-bromo-1-indanone) by Procedure A (30 min at 170° C.). The product was isolated by preparative LCMS to give the title compound as the free base and as a mixture of enantiomers (white solid, mp 242-243° C.). MS(ES+) m/z 328 ([M+1]+, 100). 1NMR (DMSO-d6) δ 1.92 (m, 1H), 2.50 (m, 1H), 2.83 (m, 1H), 2.95 (m, 1H), 5.35 (m, 1H), 6.82-7.02 (m, 3H), 7.12-7.35 (m, 4H), 7.46 (s, 1H), 10.7 (s, 1H).
