Participants

Reaction Steps

To a solution of Boc-Ala (100 mg, 0.53 mmol), HATU (261 mg, 0.69 mmol) and triethylamine (0.15 mL, 1.1 mmol) in DMF (2 mL) was added a solution of 1-pyridin-2-yl-cyclopropylamine (80 mg, 0.60 mmol) in DMF (1 mL). The mixture was stirred for 1.5 h then diluted with EtOAc (30 mL), washed with water (3×30 mL), brine (1×25 mL), dried with MgSO4, filtered, and concentrated to afford a crude solid. The crude material was purified by flash chromatography on silica gel, eluting with Hex/EtOAc (50/50 to 75/25) to afford [(S)-1-(1-pyridin-2-yl-cyclopropylcarbamoyl)-ethyl]-carbamic acid tert-butyl ester (120 mg, 74%) as a white solid.
