Procedure

To #73 (100 mg, 0.174 mmol, 1 eq.) in dichloromethane (4 mL, 0.04 M) and N,N-dimethylformamide (0.5 mL) was added #93 (59.1 mg, 0.174 mmol, 1 eq.), followed by diisopropylethylamine (92 μL, 0.52 mmol, 3 eq.) and HATU (102 mg, 0.260 mmol, 1.5 eq.). The reaction was stirred for 18 hours and then concentrated in vacuo. The residue was taken up in ethyl acetate (6 mL) and was washed with 1 M aqueous hydrochloric acid solution (2×2 mL) and with brine. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo. Purification by silica gel chromatography (Gradient: 0% to 50% acetone in heptane) provided #96 (102 mg, 65%) as a white solid. LC-MS: m/z 896.7 [M+H+], 918.8 [M+Na+], retention time=1.14 minutes; 1H NMR (400 MHz, DMSO-d6), presumed to be a mixture of rotamers, characteristic product signals: δ 7.88 (d, J=7.4 Hz, 2H), [7.83 (br dd, J=6, 5 Hz) and 8.03 (br dd, J=6, 5 Hz), total 1H], 7.67-7.73 (m, 2H), 7.36-7.48 (m, 3H), 7.22-7.35 (m, 4H), 7.13-7.21 (m, 3H), 6.86-6.96 (m, 1H), [4.44 (dd, J=8.6, 8.6 Hz) and 4.50 (dd, J=8.6, 8.6 Hz), total 1H], 3.18, 3.19, 3.26 and 3.29 (4 s, total 6H), 2.96 and 3.11 (2 br s, total 3H), 0.70-0.77 (m, 3H).
