Procedure
A mixture of 13.3 grams (0.120 mole) of m-fluoroaniline and 20.9 ml. (0.150 mole of triethylamine in 120 ml. of toluene is treated by dropwise addition with 22.5 grams (0.129 mole) of 3-ethyl-5-methyl-4-isoxazole carbonyl chloride in 100 ml. of toluene while maintaining the temperature between 30°-35° during addition. The mixture is stirred at room temperature overnight, filtered and the filtrate washed with 2N hydrochloric acid. The toluene is dried and evaporated with the residue recrystallized from toluene to give N-(m-fluorophenyl)-3-ethyl-5-methyl-4-isoxazole carboxamide (m.p. 99.5°-101° C.).
