Reaction Steps

A solution of methyl 2-{N-methyl-N-[(R/S)-α-hydroxycarbonylmethyl-4-(3,5-bistrifluoromethylbenzyloxy)phenylacetyl]amino}-(R)-propionate 48f (0.3 g, 0.56 mmol), methylamine hydrochloride (68 mg, 1 mmol) and DIEA (0.35 mL, 2 mmol) in DMF (5 mL) was cooled in an ice bath and to it was added BOP (265 mg, 0.6 mmol). After stirring at room temperature for 1 hour, EtOAc was added and the solution was washed with NaHCO3 and brine, dried over MgSO4, and concentrated to give the amide (312 mg, 100%) as a solid. MS (ESI): (M+Na)+=571.8.
