Reaction Steps

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (116 mg, 0.6 mmol) followed by 1-hydroxybenzotriazole hydrate (81 mg, 0.6 mmol) and triethylamine (84 μl, 0.6 mmol) were added to a solution of 3-methoxypropionic acid (63 mg, 0.6 mmol) in dichloromethane (10 ml) and the solution stirred for 10 minutes. The amine from example 4 (150 mg, 0.4 mmol) was added and the reaction stirred at room temperature for 5 hours. The reaction was washed with saturated sodium bicarbonate solution, dried over magnesium sulphate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (95:5:0.5) to give the title compound as a white solid, 166 mg.
