Procedure

8-(2-Chlorophenyl)-2,2 dimethyl-8-(1,4,6,7-tetrahydro-pyrrolo[3,2-c]pyridine-5-yl)-octanoic acid (0.09 g, 0.22 mmol) was dissolved in diethyl ether (5 mL) and added to HCl solution (2N HCl in diethyl ether). Water (5 mL) was added and after mixing the organic layer was discarded. The aqueous solution was freeze dried to afford 8-(2-chlorophenyl)-2,2 dimethyl-8-(1,4,6,7-tetrahydro-pyrrolo[3,2-c]pyridine-5-yl)-octanoic acid, hydrochloride salt (Compound Iq hydrochloride, 0.09 g, 86.5% yield) as a light yellow powder. 1H NMR (Field: 300 MHz, Solvent: CD3OD/TMS) δ (ppm): 10.28 (br, 1H), 7.61 (br s, 1H), 7.48-7.40 (m, 3H), 6.57 (d, 1H, J=10.8 Hz), 5.86-5.70 (2 s, 1H), 4.79-4.52 (m, 3H), 4.19-3.86 (m, 2H), 3.45-2.77 (m, 4H), 2.22-2.06 (m, 2H), 1.26-0.65 (m, 8H), 0.97 (s, 6H). (mixture of conformation isomers in NMR). 13C NMR (Field: 75 MHz, Solvent: CDCl3/TMS) 6 (ppm) 181.66, 137.12, 132.64, 132.39, 129.68, 122.62, 119.72, 109.61, 105.95, 105.76, 66.09, 51.79, 50.73, 43.06, 41.57, 37.95, 31.80, 30.52, 26.59, 25.78, 21.67.
