실험 절차

To a solution of the crude 1-benzo[1,3]dioxol-5-yl-cyclopropanecarbonyl chloride (3.0 mmol) in CH2Cl2 (30 mL) at ambient temperature was added a solution of 3-bromo-4-methoxybenzenamine (3.3 mmol), Et3N (15 mmol), and CH2Cl2 (90 mL) dropwise. The mixture was allowed to stir for 16 h before it was diluted with CH2Cl2 (500 mL). The solution was washed with 1N HCl (2×250 mL), sat. aq. NaHCO3 (2×250 mL), then brine (250 mL). The organics were dried over Na2SO4, filtered, and concentrated in vacuo to provide 1-(benzo[d][1,3]dioxol-5-yl)-N-(3-bromo-4-methoxyphenyl)cyclopropane-carboxamide (B-10) with suitable purity to be used without further purification.
