Participants

Reaction Steps

To a solution of (S)-3-cyclopropyl-2-[(5-cyclopropyl-6-cyclopropylmethoxy-pyridine-2-carbonyl)-amino]-propionic acid (100 mg, 0.29 mmol) in DMF (3 mL), was added TBTU (103 mg, 0.319 mmol), DIEA (249 μL, 1.45 mmol) and finally 1-amino-3-pyrrolidinol (CAN 887591-10-8, 30 mg, 0.29 mmol). The reaction mixture was stirred for 16 h at room temperature, concentrated in vacuo and purified by flash chromatography (silica gel, 10 g, 0% to 20% methanol in dichloromethane) to give the title compound, an epimeric mixture of products, (90 mg, 72%) as white foam; LC-MS (UV peak area/ESI) 96%, 429.2493 (M+H)+.
