PROCEDURE

实验过程

According to the general procedure D, from #176 (100 mg, 0.170 mmol, 1 eq.), (S)-1-(tert-butoxycarbonyl)-2-methyl-L-proline (50.7 mg, 0.221 mmol, 1.3 eq.), dichloromethane (4.3 mL), HATU (84.9 mg, 0.221 mmol, 1.3 eq.) and N,N-diisopropylethylamine (0.123 mL, 0.697 mmol, 4.1 eq.), was synthesized the crude desired material, which was purified by silica gel chromatography (Gradient: 0 to 100% ethyl acetate in heptane) to afford #181 (142 mg, assume quantitative yield). LC-MS (Protocol Q1): m/z 800.6 [M+H+], retention time=1.11 minutes.
