실험 절차

To a stirred solution of methyl 3-(((trans)-4-((tert-butoxycarbonyl)(methyl)amino)cyclohexyl)(ethyl)amino)-5-(3-hydroxyprop-1-yn-1-yl)-2-methylbenzoate (1.2 g, 2.62 mmol) in DCM (15 mL), PPh3 (1.37 g, 5.22 mmol) and CBr4 (1.7 g, 5.10 mmol) were added at 0° C. and reaction was stirred for 4 h at room temperature. On completion, reaction was quenched with ice water and extracted with dichloromethane. The combined organic layers were washed with water, dried, concentrated under reduced pressure. The crude material was purified by column chromatography to afford the title compound (0.5 g, 38.5% yield).
