PROCEDURE
实验过程
To a stirred solution of (2R,5R)-4-{2-[6-(2-fluoro-benzyl)-3,3-dimethyl-2,3-dihydro-pyrrolo[3,2-c]pyridin-1-yl]-2-oxo-ethyl}-5-hydroxymethyl-2-methyl-piperazine-1-carboxylic acid tert-butyl ester (0.572 g, 0.97 mmol) and triethylamine (0.22 mL, 0.157 g, 1.55 mmol) in DCM (10 mL) at −10° C. under nitrogen was added a solution of methanesulfonyl chloride (0.09 mL, 0.133 g, 1.2 mmol) in DCM (5 mL). Mixture was stirred at 20° C. for 18 h then partitioned between saturated aqueous NaHCO3 (50 mL) and DCM (3×30 mL) and combined organic extracts were dried (Na2SO4) and evaporated in vacuo to give the title compound (0.576 g) as an oil, used without further purification. MS: [M+H]+=545.
