実験手順

12.2 g. of 4-chloro-3methyl-6-phenylisoxazolo[5,4-b]-pyridine (0.05 mol.) are added to 150 ml. of n-butylamine. The reaction mixture is heated at 150°-160° for 3 hours in an autoclave and, after cooling to room temperature, is evaported in vacuo. The residue is treated with water, filtered off and dried. 14.1 g. (100%) of N-butyl-3-methyl-6-phenylisoxazolo[5,4-b]pyridin-4-amine are recrystallized from a mixture of ligroin and ethylacetate (3:1), m.p. 126°-127°.
