Reaction Steps

A solution of 2H-spiro[naphthalene-1,4′-piperidine]-4-carbonitrile (A4) (66 mg, 0.3 mmol), 3,3-dimethylbutanal (46 mg, 0.46 mmol) in 1,2-dichloroethane (5 ml) was stirred at 40° C. for 2 h. To the solution was added sodium triactoxyborohydride and the resulting mixture was stirred overnight, followed by treatment of MeOH (1 ml). Evaporation and the residue was dissolved in MeOH (2 ml) and purified by reverse phase C-18 HPLC to give 1′-(3,3-dimethylbutyl)-2H-spiro[naphthalene-1,4′-piperidine]-4-carbonitrile (Compound No. 51). LC-MS: m/e=309.1 (M+H). Rt=1.92 min. 1H-NMR (500 MHz, DMSO-d6): 9.03 (br. s, 1H), 7.49-7.40 (m, 4H), 7.12 (t, 1H), 3.45 (d, 2H), 3.22-3.11 (m, 4H), 2.78 (d, 2H), 2.03 (td, 2H), 1.88 (d, 2H), 1.58-1.54 (m, 2H), 0.92 (s, 9H).
