Reaction Steps

4-(4-Pyridyl)butanoic acid 10-5 (100 mg, 1.8 mmol), H—Sar—OEt. HCl (300 mg, 2.0 mmnol), BOP (965 mg, 2.2 mmol) and NMM (700 μL, 6.4 mmol) were combined in 9 mL DMF. After stirring overnight the mixture was diluted with EtOAc, washed with water (4×), sat. NaHCO3, and brine, dried (MgSO4), filtered and concentrated. Flash chromatography (silica, 80% to 100% EtOAc/hexane) provided 6-1 as a colorless oil.
