실험 절차

A mixture of intermediate 147(d) obtained from example 147 (184 mg, 0.5 mmol), 4-(tributylstannyl)-1-methyl-1H-imidazole (223 mg, 0.6 mmol) and Pd(PPh3)Cl2 (35 mg, 0.05 mmol) in THF (3 mL) was heated in a microwave oven (Personal Chemistry) for 2 hours at 130° C. The mixture was concentrated and the residue was purified by silica gel chromatography (5% MeOH/EtOAc) to give the title compound (110 mg, 0.289 mmol) in 59% yield as an orange powder.
