Versuchsvorschrift

To a mixture of #105 (225 mg, 0.289 mmol, 1 eq.) in dichloromethane (15 mL, 0.02 M) and N,N-dimethylformamide (1 mL) was added HATU (136 mg, 0.347 mmol, 1.2 eq.). After five minutes, a solution of amine #102 (72.4 mg, 0.318 mmol, 1 eq.) and diisopropylamine (203 mL, 1.16 mmol, 3 eq.) in dichloromethane (5 mL) was added. After 24 hours, the reaction mixture was washed with brine, dried over sodium sulfate, filtered, concentrated in vacuo onto silica gel, and purified by silica gel chromatography (Gradient: 0% to 50% acetone in heptane) to give the single enantiomer #106 (210 mg, 76%) as a clear oil. LC-MS: m/z 953.1 [M+H+], retention time=3.99 minutes; 1H NMR (400 MHz, CDCl3), presumed to be a mixture of rotamers, characteristic signals: 7.76 (d, J=7.5 Hz, 2H), 7.57-7.64 (m, 2H), 7.40 (dd, J=7.5, 7.4 Hz, 2H), 7.28-7.34 (m, 2H), 4.82-4.88 (m, 1H), 3.95-4.01 (m, 1H), 3.76 and 3.82 (2 s, total 3H), 3.30, 3.31, 3.34 and 3.35 (4 s, total 6H), [1.20 (d, J=7.0 Hz) and 1.20 (d, J=7.0 Hz), total 3H].
