Procedure

According to general procedure D, from #8 (247 mg, 0.387 mmol, 1 eq.), #39 (186 mg, ≦0.450 mmol, 1.2 eq.), dichloromethane (10 mL, 0.04 M), N,N-dimethylformamide (2 mL), HATU (176 mg, 0.464 mmol, 1.2 eq.) and triethylamine (189 mL, 1.35 mmol, 3.5 eq.) was synthesized the crude desired material, which was purified by silica gel chromatography (Gradient: 0% to 25% acetone in heptane) to give #40 (410 mg, 90% over 2 steps) as an off-white solid. LC-MS: m/z 984.7 [M+H+], 1006.7 [M+Na+], retention time=1.15 minutes; HPLC (Protocol C): retention time=9.683 minutes (purity >99%); 1H NMR (400 MHz, DMSO-d6), presumed to be a mixture of rotamers, characteristic signals: δ [10.19 (br d, J=7 Hz) and 10.49 (br d, J=8 Hz), total 1H], 7.90 (d, J=7.5 Hz, 2H), 7.60-7.65 (m, 2H), 7.38-7.45 (m, 2H), 7.29-7.35 (m, 2H), 7.14-7.28 (m, 5H), [5.20 (ddd, J=11, 7, 4 Hz) and 5.35-5.43 (m), total 1H], 3.65 and 3.69 (2 s, total 3H), [1.15 (d, J=6.5 Hz) and 1.18 (d, J=6.4 Hz), total 3H].
