N- 4-Isoxazolyl formamide

This is prepared from 4-(A -benzylamino)isoxazole by the same procedure as for A -(4-isoxazolyl)formamide above. Thus, reaction of 4-(A7-benzylamino)isoxazole (0.843 g, 4 mmol) gives, after flash chromatography [34] (ethyl acetate-isopropyl ether, 2 8), a yellow solid (0.714g, 88%), m.p. 71-73 C. 

This is prepared from iV-benzyl-iV-(4-isoxazolyl)formaiiiide by the general procedure to give a yellow oil (after flash chromatography) which solidifies on standing (53%). The product is recrystallized from pentane, m.p. 53-55°C.
