Reaction Steps

Benzoyl chloride (21 μl, 0.18 mmol, 1.0 equivalents) was added in one portion to a solution of 2-allyloxycarbonylamino-3-(3-pyrrolidin-2-yl-isoxazol-5-yl)-propionic acid ethyl ester hydrochloride (1C) (74 mg, 0.20 mmol, 1.1 equivalents) in pyridine (29 μl, 0.36 mmol, 2.0 equivalents) and dichloromethane (2 mL) at 0° C. The reaction was stirred at room temperature for 4 hours then diluted with ethyl acetate (30 mL). The reaction was extracted with 1N hydrochloric acid (30 mL) and brine (30 mL). The organic portion was dried over sodium sulfate and concentrated in vacuo to give the title compound (66 mg, 84%). MS (Cl) m/z 442.3 (M+1).
