Procedure

To a solution of Boc-L-cyclohexylglycine (172 mg, 0.67 mmol) in NMP (2 mL) was added HATU (255 mg, 0.67 mmol) followed by NMM (0.1 mL, 0.95 mmol). After 5 min, 81 (190 mg, 0.55 mmol) in DCM (1 mL) was added and the reaction mixture was stirred at room temperature overnight. Ethyl acetate (20 mL) was added to the reaction mixture and the organic solution was washed with water, 1 N HCl (5 mL), aqueous NaHCO3 (10 mL), and brine, dried over Na2SO4. Solvent was removed under reduced pressure and the product was purified by flash silica gel chromatography to afford 280 mg (85%) of 82 as a wax.
