reacted with acrylonitrile, N‐tolyl‐maleimide and active methylene compounds to afford the isoxazoline 4, the pyrrolidino[3,4‐d]isoxazoline 5 and the isoxazole derivatives 6,7, respectively. Nitrosoimidazo[1,2‐a]pyridines 10 and the imidazo[1,2‐a]pyrimidine 12 were obtained by the reaction of 3 with 2‐aminopyridine and 2‐aminopyrimidine, respectively. 3 reacted also with o‐phenylenediamine and o‐aminothiophenol
