Versuchsvorschrift
To a suspension of 108 g of stannous chloride dihydrate in 270 ml of concentrated hydrochloric acid was added portionwise 30 g of 4-(2-nitrophenyl)isoxazole prepared in Example 10 at less than 30° C. The suspension was stirred at about 20°-35° C. for 10 hours, then cooled to 10° C. and filtered. The solid was added to ice-water (400 ml), 50% NaOH was added to make the suspension basic to a pH of about 10, and the resultant suspension filtered. The solid was washed 3×100 ml of water and suction dried to give 18 g of the title compound; m.p. 48°-51° C.
