Versuchsvorschrift

Benzoyl chloride (0.33, 2.3 mmol) was added dropwise to a solution of (±)-4-((αR*)-α-((2S*,5R*)-4-allyl-2,5dimethyl-1-piperazinyl)-3-hydroxybenzyl)-N,N-diethylbenzamide (0.92 g, 2.1 mmol) (Example 6) and triethylamine (0.60 mL, 4.2 mmol) in 20 mL dichloromethane. The reaction mixture was stirred for 1 hour and then was washed twice with 20 mL of water, dried over sodium sulfate, and concentrated to dryness. The residue was purified by chromatography on silica gel with dichloromethane:ethanol to give 0.92 g (74%) of (±)-3-((αR*)-α-((2S*,5R*)-4-allyl-2,5-dimethyl-1-piperazinyl)-4-(diethylcarbamoyl)benzyl)phenyl benzoate. NMR (300 MHz, CDCl3): δ 0.9 (d, 3H); 1.2 (d, br t, 9H); 1.9 (t, J=11 Hz, 1H); 2.1 (dd, 1H); 2.5 (br m, 1H); 2.6 (m, 2H); 2.8 (m, 2H); 3.2-3.6 (br m, 5H); 5.2 (2d, 2H); 5.3 (s, 1H); 5.8 (m, 1H); 7-7.2 (2d, s, 3H); 7.3 (m, 3H); 7.5 (m, 4H); 7.6 (t, 1H), 8.2 (d, 2H).
