実験手順
methyl 2-(5-bromo-2-(2-((tert-butoxycarbonyl)amino)acetyl)-1,2,3,4-tetrahydroisoquinolin-1-yl)acetate. To a stirred solution of methyl 2-(5-bromo-1,2,3,4-tetrahydroisoquinolin-1-yl)acetate (76 g, 267 mmol), Boc-glycine (51.5 g, 294 mmol) and triethylamine (74.6 mL, 535 mmol) in AcOEt (1350 mL), T3P (191 mL, 321 mmol, 50% m/m in AcOEt) was added and the solution was stirred at RT for 90 min. 0.2N aqueous HCl (400 mL) was added and the reaction mixture was stirred for 5 min. The organic layer was separated and washed with 0.2 N aqueous HCl (1×250 mL), saturated aqueous NaHCO3 (2×250 mL) and brine (1×250 mL). The combined organic layers were dried with sodium sulfate, filtered and the solvent was removed under reduced pressure. The residue was dried under high vacuo overnight to yield the title compound as white foam (113 g) which was used without further purification. UPLC-MS: MS 441.2/443.2 (M+H+); UPLC rt 1.12 min.
