Reaction Steps
N-(4-bromo-3-methyl-5-isoxazolyl)diphenyl phosphinic amide was prepared by the method of Example 3 with 4-bromo-3-methyl-5-amino isoxazole (0.18 g, 1.0 mmol), THF (5 ml), NaH (60% oil dispersion, 88 mg, 2.2 mmol), and diphenyl phosphinic chloride (0.23 ml, 1.2 mmol). Recrystallization three times from chloroform and hexanes provided 0.17 g (45%) of faint pink crystals, m.p. 178.5-181° C.
