Reaction Steps
Cyclopropylamine (2.85 g.) is added to a suspension of 2-(7-chloro-1,8-naphthyridin-2-yl)-3-phenoxycarbonyloxy-isoindolin-1-one (4.3 g.) in acetonitrile (43 cc.), and the suspension obtained is stirred for 20 hours at a temperature of about 20° C. Diisopropyl ether (85 cc.) is then added, after which the insoluble product is filtered off and washed with diisopropyl ether (2 × 10 cc.). Recrystallisation from acetonitrile (130 cc.) gives 2-(7-chloro-1,8-naphthyridin-2-yl)-3-cyclopropylaminocarbonyloxy-isoindolin-1-one (3.2 g.) melting at 220° C.
