実験手順

To the stirred suspension of 3-methoxy-pyrrolidine-1,3-dicarboxylic acid 1-tert-butyl ester 6BV (4.16 mmole, crude) in DMF/DCM (25 mL/25 mL), 3-(2-methoxypyridin-4-yl)-1-trityl-1H-indazol-5-ylamine 5BV (2.008 g, 4.16 mmole) and Et3N (2.9 mL, 21 mmole) were added at r.t. under dry N2 gas followed by HATU (3.16 g, 8.32 mmole). The mixture was stirred at r.t. under dry N2 gas overnight. The mixture was partitioned between 1:1 EtOAc and sat. NaHCO3 solution. The organic phase was separated, washed with brine, dried over MgSO4 and evaporated to dryness. The crude solid was purified on RediSep 120 g cartridge eluting with 10-25% EtOAc/Hexanes to yield a brown solid 7BV (2.95 g, 100%).
