실험 절차

N-Methyl-2,4,6-trichloroaniline [NMR (200 MHz, CDCl3): δ 2.82 (s, 3H); 5.11 (s, 1H); 7.46 (s, 2H)] was prepared from 2,4,6-trichloroaniline, coupled with 3-((αR)-α-((2S, 5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-(tert-butyldimethylsilyloxy)benzyl)benzoyl chloride, deprotected and purified by the methods described in Example 10 to give (+)-3-((αR)-α-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-hydroxybenzyl)-N-methyl-N-(2,4,6-trichlorophenyl) as an off-white powder.
