Procedure
The compound was prepared in a manner similar as to that described for 1-[6-(4-tert-Butyl-cyclohexyloxy)-naphthalen-2-ylmethyl]-4-ethyl-piperidine-4-carboxylic acid using 4-Phenyl-piperidine-4-carboxylic acid (0.198 g, 0.967 mmol), 6-(4-tert-Butyl-cyclohexyloxy)-naphthalene-2-carbaldehyde (0.250 g, 0.805 mmol), acetic acid (0.16 mL, 2.8 mmol), Methanol (1.6 mL, 4.0E1 mmol) and sodium cyanoborohydride (75.314 mg, 1.1985 mmol) to give 21 mg of the title compound as a white solid (5%). ESI-LCMS (500 M+H). 1H NMR (DMSO-d6, 400 MHz): Shift (ppm) 7.80-7.98 (m, 3H), 7.16-7.63 (m, 8H), 4.51 (br. s., 3H), 3.45-3.64 (m, 2H), 2.96-3.18 (m, 2H), 2.68 (m, 2H), 2.13-2.31 (m, 2H), 1.74-2.09 (m, 4H), 1.00-1.53 (m, 5H), 0.89 (s, 9H)
