実験手順

A suspension of (R)-benzyl 3-(4-butoxy-4-oxobutanamido)-4-(3′-chlorobiphenyl-4-yl)butanoate (178.9 mg, 0.334 mmol) and Pd/C (71.0 mg, 0.033 mmol) in EtOAc (3 ml) is allowed to stir under hydrogen at room temperature for 1.5 hours. The reaction mixture is filtered, and concentrated to give crude. The resulting residue is purified by preparative HPLC using a gradient of 20% MeCN/water (0.1% TFA) to 100% MeCN to give (R)-3-(4-butoxy-4-oxobutanamido)-4-(3′-chlorobiphenyl-4-yl)butanoic acid (90.7 mg) as a white solid; HPLC retention time=1.27 minutes (condition B); MS (m+1)=446.24; 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 0.91 (t, J=7.5 Hz, 3H) 1.31-1.40 (m, 2H) 1.55-1.62 (m, 2H) 2.43-2.47 (m, 2H) 2.52-2.69 (m, 4H) 2.93 (A of ABX, Jab=3.7 Hz, Jax=7.7 Hz, 1H) 3.00 (B of ABX, Jab=13.7 Hz, Jbx=6.8 Hz, 1H) 4.07 (t, J=6.7 Hz, 2H) 4.49-4.57 (m, 1H) 6.31 (br d, J=8.6 Hz, 1H) 7.26-7.37 (m, 4H) 7.43-7.46 (m, 1H) 7.49-7.52 (m, 2H) 7.55 (br t, J=1.8 Hz, 1H).
