実験手順
A mixture of 24.2 g (82.5 mmol) of 2-({6-methoxy}-1H-indazol-3-yl)-1H-isoindole-1,3(2H)-dione and 73.4 g (0.635 mol) of piridine hydrochloride was heated at 200° C. for 4 hours. The resulting brown solution was cooled to 140° C. and slowly poured in a well stirred mixture of 250 ml of 0.2 N HCl and 350 ml of ethyl acetate. The organic layer was separated and the aqueous layer was salted (45 g of NaCl) and extracted twice with 350 ml of ethyl acetate. Organic extracts were dried over sodium sulfate and concentrated under vacuum to small volume. The precipitate was filtered off and dried: 15.89 g of product as yellow solid were obtained. Yield=68.9%. mp=265-270° C. dec.
