Reaction Steps

17.5 g (0.0568 mol) of the product of Step (1) was added and dissolved in a mixture of ethanol (60 ml) and water (60 ml). Then, 39.5 g (0.568 mol) of hydroxylamine hydrochloride and 77.2 g (0.568 mol) of sodium acetate trihydrate were added thereto, and the mixture was reacted at 60° C. for 18 hours under stirring. Formed precipitates were collected by filtration, washed sequentially with water, ethanol and ethyl ether, and then dried to obtain 8.1 g (yield: 44.0%) of the above identified compound.
