Reaction Steps

A solution of 4-(2-benzyloxy-ethyl)-2-(4-bromo-phenyl)-5-methyl-oxazole (200 mg, 0.538 mmol) in toluene (5.0 mL) in a seal tube under nitrogen gas flow was treated with Pd(OAc)2 (50 mg), 2-(di-t-butylphosphino)biphenyl (20 mg), N-methyl aniline (115 mg, 1.08 mmol), and sodium t-butoxide (104 mg, 1.08 mmol). The tube was sealed and heated at 105° C. for 14 h. The mixture was cooled and purified directly by silica gel column chromatography (30-50% EtOAc/hexanes) to yield the title compound (195 mg, 91%). MS (ESI) m/z 399.3 (M+H)+.
