Reaction Steps

According to general procedure D, from #32 (550 mg, 0.902 mmol, 1 eq.), #58 (350 mg, 0.992 mmol, 1.1 eq.) dichloromethane (10 mL, 0.08 M) and N,N-dimethylformamide (2 mL), HATU (446 mg, 1.17 mmol, 1.3 eq.) and triethylamine (0.503 mL, 3.61 mmol, 4 eq.) was synthesized the crude desired material, which was purified by silica gel chromatography (Gradient: 0% to 30% acetone in heptane), producing #59 (618 mg, 69%) as an off-white solid. LC-MS: m/z 908.7 [M+H+], 930.7 [M+Na+], retention time=1.07 minutes; HPLC (Protocol B at 45° C.): m/z 908.5 [M+H+], retention time=8.721 minutes (purity >97%); 1H NMR (400 MHz, DMSO-d6), presumed to be a mixture of rotamers, characteristic signals: δ 7.89 (d, J=7.5 Hz, 2H), 7.38-7.44 (m, 2H), 7.30-7.36 (m, 2H), [4.49 (dd, J=8.5, 7.8 Hz) and 4.59 (dd, J=8.7, 6.9 Hz), total 1H], 4.18-4.26 (m, 3H), 3.93-4.01 (br m, 1H), 3.23 and 3.26 (2 s, total 3H), 3.16 and 3.16 (2 s, total 3H), 2.91 and 3.05 (2 br s, total 3H), 1.36 and 1.37 (2 br s, total 3H), 1.30 and 1.32 (2 br s, total 3H), [1.00 (d, J=6.7 Hz) and 1.02 (d, J=6.6 Hz), total 3H], 0.67-0.78 (m, 7H).
