Reaction Steps

A solution of the nitrile (A3) (300 mg) in dichloromethane (3 ml) was treated with TFA (1 ml) for 1 hour, concentrated, co-evaporated with acetonitrile and dissolved in dichloromethane (ca. 100 ml). The resulting solution was washed with a mixture of brine (ca. 20 ml) and 6N NaOH (2 ml), dried over Na2SO4, and concentrated to give 2H-spiro[naphthalene-1,4′-piperidine]-4-carbonitrile (A4) as a white solid. LC-MS: m/e=225.2 (M+H). Rt=1.53 min.
