The mixture was diluted with [1 M HCI] (100 mL) and [CH2CI2] (150 mL), and the layers were separated. The organic phase was washed with 1 M HCI (1 x 100 mL), 1N NaOH (1 x 100 mL) and brine [(1] x 100 mL). The organic layer was dried over [NA2SO4,] and then filtered, and the solvent was removed under reduced pressure. Purification on silica gel (0-15% EtOAc in hexane) gave 12.0 g (99%) of desired ester as a white [SOLID.'H] NMR (400 MHz, [CDCI3)] : 8.15 (d, [J=8. 6HZ,] 2H), 7.99 (d, [J=8. 6HZ,] 2H), 7.18 (t, J = 7.6 Hz, 1H), 7.10 (d, J = 7.6 Hz, 1 H), 6.87 (m, 2H), 3.97 (s, 3H), 3.93 (dd.
