Procedure
Alkylation of 4-((alpha-R)-alpha-((2S,5R)-4-benzyl-2,5-dimethyl-1-piperazinyl)-3-hydroxybenzyl)-N,N-diethylbenzamide (Example 12) with ethyl iodoacetate, and subsequent hydrolysis of the ester as in Example 14 gave the title compound (84.6%) 1H NMR (0.1-M NaOD in CD3OD, 300 MHz); δ 1.10 (d, J=5.0 Hz, 3H); 1.11 (d, J=5.8 Hz, 3H; both doublets superimposed on m, 3H); 1.23 (m, 3H); 2.03 (m, 2H); 2.57 (m, 2H); 2.69 (m, 2H); 3.30 (m, 3H, superimposed on br m, 2H); 3.88 (d, J=13.1 Hz, 1H); 4.35 (s, 2H); 5.16 (s, 1H): 6.83 (m, 2H); 6.88 (s, 1H); 7.25 (m, 8H); 7.52 (d, J=8.1 Hz, 2H). Mass spectrum: (PFAB, glycerol matrix subtracted): m/z: 544.8, ((M+1)+, 82%).
