(a) 5-Amino-4-bromo-3-methylisoxazole 5-Amino-3-methylisoxazole (0.98 g, 10 mmol) was dissolved in chloroform (15 ml) and cooled to 0 C. N-Bromosuccinimide (1.78 g, 10 mmoles) was added in small portions over a period of 10 min. The stirring was continued for another 10 minutes at 0 C. The reaction mixture was diluted with chloroform (50 ml), washed with water (2*50 ml) and the organic layer was dried over magnesium sulfate. Removal of the solvent under reduced pressure gave the crude product, which was purified by column chromatography using 9: 1, hexanes/ethyl acetate as the eluent, to give 5-amino-4-bromo-3-methylisoxazole (1.55 g, 87% yield).
