Reaction Conditions

Reaction Steps

A mixture of 5-amino-2-benzofuran-1(3H)-one (100 mg, 0.67 mmol), benzyl bromide (319 μl, 2.68 mmol), and diisopropylethylamine (350 μl, 2.01 mmol) in THF (2.0 ml) was heated at 50° C. for 65 hours. The reaction was partitioned between water and EtOAc. The organic layer was washed with water, brine, dried with Na2SO4 and rotary evaporated. The yellow oil was triturated at room temperature with 10% EtOAc/hexane and then chromatographed (20% to 40% EtOAc/hexane gradient) to give 5-dibenzylamino-3H-isobenzofuran-1-one as a white solid (136 mg, 31%).
