To a stirred solution of N-methoxy-N-methylamine hydrochloride (0.980 g, 10.0 mmol) in DMF (25 mL) was added N-methylmorpholine (1.21 mL, 11.0 mmol), HOBt (1.50 g, 11.1 mmol), 3-(2-pyridyl)-phenylacetic acid (2.36 g, 11.1 mmol), and EDC (2.13 g, 11.1 mmol). The reaction was stirred overnight whereupon it was poured into a rapidly-stirred mixture of 150 mL each of EtOAc, 10% NaHCO3, and brine. After stirring for 30 min, the layers were separated and the aqueous layer was washed with fresh EtOAc (150 mL). The combined organic layers were washed with 10% Na2CO3, and brine, then dried (MgSO4), filtered, and concentrated. Column chromatography (silica gel, 3:1 EtOAc:hexane) gave 2.275 g of the title compound: MS (ES+) (MH+) 257.2.
