Versuchsvorschrift

According to general procedure D, from #32 (353 mg, 0.488 mmol, 1 eq.) in dichloromethane (10 mL, 0.04 M), amine #67 (271 mg, ≦0.588 mmol, 1.3 eq.), HATU (223 mg, 0.586 mmol, 1.2 eq.) and diisopropylethylamine (238 μL, 1.71 mmol, 3.5 eq.) was synthesized the crude desired material, which was purified by silica gel chromatography (Gradient: 0% to 40% acetone in heptane), affording #68 (404 mg, 88% over two steps) as a solid. LC-MS: m/z 940.7 [M+H+], 962.7 [M+Na+], retention time=1.04 minutes; HPLC (Protocol C): retention time=9.022 minutes; 1H NMR (400 MHz, DMSO-d6), presumed to be a mixture of rotamers, characteristic signals: δ [8.25 (br d, J=8 Hz) and 8.48 (br d, J=8 Hz), total 1H], 7.89 (d, J=7.4 Hz, 2H), 7.67-7.75 (m, 2H), 7.38-7.44 (m, 2H), 7.31-7.36 (m, 2H), 7.14-7.24 (m, 5H), 4.43-4.69 (m, 3H), 4.17-4.26 (m, 3H), 3.91-3.99 (br m, 1H), 3.63 and 3.65 (2 s, total 3H), 3.19 and 3.24 (2 s, total 3H), 3.14 and 3.15 (2 s, total 3H), 2.90 and 2.99 (2 br s, total 3H), 1.36 and 1.37 (2 br s, total 3H), 1.30 and 1.32 (2 s, total 3H), [1.02 (d, J=6.8 Hz) and 1.06 (d, J=6.6 Hz), total 3H].
