実験手順
7-(2-Chlorophenyl)-2,2 dimethyl-7-(1,4,6,7-tetrahydro-pyrrolo[3,2-c]pyridine-5-yl)-heptanoic acid (0.26 g, 0.67 mmol) was dissolved in diethyl ether (15 mL) and hydrogen chloride solution (2N HCl in diethyl ether) was added. The ether solution was extracted with water (15 mL) and the organic layer was discarded. The aqueous solution was freeze dried to afford 7-(2-chlorophenyl)-2,2 dimethyl-7-(1,4,6,7-tetrahydro-pyrrolo[3,2-c]pyridine-5-yl)-heptanoic acid, hydrochloride (Compound Ik hydrochloride, 0.19 g, 61.9% yield) as a light yellow powder (purity 97.33% by HPLC, mp. 168-172° C.). 1H NMR (Field: 300 MHz, Solvent: CD3OD/TMS) δ (ppm): 10.26 (br s, 1H), 7.65 (br s, 1H), 7.45-7.38 (m, 4H), 6.54-6.50 (2 s, 1H), 5.84 (s, 0.5H), 5.66 (s, 0.5H), 4.79 (m, 1H), 4.51 (m, 1H), 4.14-3.82 (m, 2H), 3.43-2.76 (m, 4H), 2.43-2.09 (m, 2H), 1.25-1.14 (m, 4H), 1.39-0.65 (m, 2H), 0.96 (s, 6H). (mixture of conformational isomers). 13C NMR (Field: 75 MHz, Solvent: CDCl3/TMS) δ (ppm) 181.52, 137.17, 132.64, 132.32, 131.75, 130.09, 129.79, 122.85, 119.88, 109.70, 106.00, 65.79, 51.79, 51.10, 42.98, 41.43, 31.84, 27.28, 25.096, 25.76, 21.78. MS (HR, DIP-CI): Calculated for C22H30Cl2N2O2 (M+H)+: 389.1994, found 389.1996. CHN analysis: Calculated; 62.12 C, 7.11 H, 6.59 N, 16.67 Cl, found; 59.23 C, 7.04 H, 6.26 N, 16.93 Cl.
