実験手順
A mixture of 2-(7-chloro-1,8-naphthyridin-2-yl)-3-phenoxycarbonyloxy-isoindolin-1-one (8.6 g.) and sec-butylamine (40 cc.) is heated at 65° C. until dissolution. The reaction mixture is then diluted with diisopropyl ether (240 cc.). The precipitate formed is filtered off and recrystallised from acetonitrile (60 cc.). 2-(7-Chloro-1,8-naphthyridin-2-yl)-3-sec-butylaminocarbonyloxy-isoindolin-1-one (3 g.), melting at 220°-222° C., is thus obtained.
