HCID 86754778(2-Oxo-3-(2-(5,6,7,8-tetrahydro[1,8]-naphthyridin-2-yl)ethyl)pyrrolidin-1-yl)acetyl-3(S)-ethynyl-beta-alanine ethyl ester

Procedure

To a stirred solution of 2-8 (50 mg, 0.15 mmol), 2-9 (29 mg, 0.17 mmol) (Zablocki et al., J. Med Chem., 1995, 38, 2378), NMM (83 μL, 0.75 mmol), and CH3CN (1 mL) was added BOP (74 mg, 0.17 mmol). After 20 h, the reaction mixture was diluted with EtOAc and then washed with sat. NaHCO3, H2O and brine, dried (MgSO4), and concentrated to give 2-11 as a yellow oil.

Workup

  1. washwashed with sat. NaHCO3, H2O and brine
  2. dry with materialdried (MgSO4)
