Procedure

Pyridine (10 cc.) and butyl isocyanate (11.2 cc.) are added to a suspension of 2-(7-chloro-1,8-naphthyridin-2-yl)-3-hydroxy-6-trifluoromethyl-isoindolin-1-one (3.8 g.) in acetonitrile (380 cc.). The mixture is heated to the reflux temperature and triethylamine (0.5 cc.) is added. Refluxing is continued for 50 minutes until dissolution. After cooling the solution, the precipitate formed is filtered off and washed with water (30 cc.). After drying, a first crop of 2-(7-chloro-1,8-naphthyridin-2-yl)-3-n-butylaminocarbonyloxy-6-trifluoromethyl-isoindolin-1-one (2.8 g.) is obtained.
