Reaction Steps

To a mixture of 4-benzyloxy-N-hydroxy-2-iodo-5-methoxy-benzimidoylchloride and N,N-dimethylformamide (110 mL) was added a 28% ammonia in water (12 mL) under ice-bath cooling. After stirring for 3 hours under ice-bath cooling, water and ethyl acetate were added to the mixture. The separated organic layer was washed with water and brine successively, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was triturated with hexane:diethyl ether=1:4 to give the title compound (9.3 g).
