実験手順

To a stirred solution of methyl 5-bromo-3-(((trans)-4-((tert-butoxycarbonyl)(methyl)amino)cyclohexyl)(ethyl)amino)-2-methylbenzoate (2 g, 4.14 mmol) in dry toluene was added CuI (0.015 g, 0.079 mmol), PPh3 (0.043 g, 0.165 mmol), PdCl2(PPh3)2 (0.058 g, 0.082 mmol), N,N-diisopropyl amine (1.08 g, 10.78 mmol) and reaction was purged with argon for 15 min. prop-2-yn-1-ol (0.46 g, 8.29 mmol) was added to it reaction was heated at 80° C. at sealed condition for 5 h. On completion, it was quenched with water and extracted with ethyl acetate. Organic layer was dried over Na2SO4. The crude compound was purified by column chromatography to afford the title compound (1.2 g, 63.2% yield).
