Procedure
To a stirred solution of 3-(2,6-Dimethylbenzyloxy)phenylacetic acid (3.08 g, 11.4 mmol) and Benzotriazol-1-yloxy-tris(dimethylamino)-phosphonium hexafluorophosphate (5.05 g, 11.4 mmol) in DMF (75 ml) was added triethylamine (2.30 g, 22.8 mmol), and the reaction mixture was stirred for 1 h at room temperature. To this reaction mixture was added liquid ammonia (100 ml) at −40 0° C., the resulting mixture was allowed to warm to ambient temperature over 10-12 hours and concentrated. The residue was taken into ethyl acetate and washed with water (2×), dried over Na2SO4, filtered, concentrated and purified by flash chromatography on a silica gel column (ethyl acetate:hexane, 2.5:1 spiked with acetic acid) to give the title compound.
