Reaction Steps
A mixture containing 3-bromo-5-methyl-isoxazole-4-carboxylic acid ethyl ester (5.0 g, 18.8 mmol), pyrrolidine (13.37 g, 188 mmol) and BEMP (10.53 g, 37.6 mmol) was heated in the microwave at 180° C. for 10 min. The mixture was then extracted with ethyl acetate, dried over potassium sulphate, filtered and evaporated. Purification by chromatography (silica, ethyl acetate:methanol 1:9 to 3:7) afforded the title compound (1.1 g, 21%) as a yellow oil. MS: m/e=225.3 [M]+.
