Participants

Reaction Steps

The same procedure as employed in the preparation of Example 15 (step d) but using ethyl ((4-aminobenzyl){cyclopentyl[4-(trifluoromethyl)phenyl]methyl}amino)(oxo)acetate and tridecanoyl chloride gave the title compound as a colorless oil (76%). 1H NMR (CDCl3, 300 MHz) δ 7.52-7.21 (m, 6H), 6.95 (d, 1H, J=8.5 Hz) 6.8 (d, 1H, J=8.5 Hz), 5.30 (m, 1H), 4.47-4.05 (m, 4H), 2.85-2.60 (m, 1H), 2.45-2.26 (m, 2H), 1.80-1.10 (m, 31H), 1.05-0.86 (m, 4H). M−(LC/MS(ESI)): 643.9; M+(LC/MS(ESI)): 645.2. HPLC (Condition A), Rt: 6.85 min (HPLC purity: 98.0%).
