Procedure

A solution of the compound of Example 281 (60 mg, 0.091 mmol), methoxyacetic acid (13 mg, 0.13 mmol), EDCl (26 mg, 0.14 mmol), and DMAP (11 mg, 0.091 mmol) in CH2Cl2 (1.5 mL) was stirred at room temperature overnight. The reaction mixture was concentrated down and the crude product was purified by preparative TLC plate with CH2Cl2:MeOH:NH4OH (90:15:2) to obtain (60 mg). ESLC-MS: m/z=725 (MH+); 1H NMR (MeOH-d4): 8.566˜8.439 (m, 2H), 8.077 (s, 1H), 7.889˜7.780 (m, 1H), 7.675 (m, 1H), 7.453 (m, 2H), 7.313(m, 2H), 6.767 (d, 1H), 5.180˜5.035 (m, 1H), 4.220 (s, b, 1H), 3.907 (s, 2H), 3.760˜3.333 (m, 4H), 2.835 (m, 2H), 2.041 (m, 1H), 1.711 (m, 1H), 1.445 (d, 9H), 0.892 (s, 9H), 0.076 (s, 3H), −0.109 (s, 3H).
