Procedure

To a stirred solution of compound 49 (150 mg, 0.289 mmol, scheme 15), Boc-L-valine (94 mg, 0.43 mmol) and triethylamine (120 μL, 0.87 mmol) in DMF (5 mL) under nitrogen were added HOBT monohydrate (49 mg, 0.32 mmol) and EDC hydrochloride (139 mg, 0.72 mmol) reagents, and the reaction mixture was stirred at RT overnight. The reaction mixture was then partitioned between AcOEt and a saturated aqueous solution of sodium bicarbonate. The organic layer was successively washed with a saturated aqueous solution of sodium bicarbonate, a saturated aqueous solution of ammonium chloride and brine, dried over anhydrous magnesium sulfate, filtered and concentrated. The crude product was purified by Biotage (Snap 25 g; MeOH/DCM: 1/99 to 10/90 over 20 CV), to afford the title compound 75 (171 mg, 0.238 mmol, 82% yield) as a colorless sticky film. MS (m/z): 718.4 (M+H).
