Reaction Conditions

Reaction Steps

To a solution of tert-butyl 2-((2-cyano-3-nitrophenoxy)methyl)piperidine-1-carboxylate (Example 26e, 1.02 g, 2.83 mmol) in EtOH (20 mL) was added HCl 1.25N in EtOH (11.3 mL, 14.13 mmol) and the reaction mixture was stirred at 80° C. under nitrogen for 1 hour. After cooling to room temperature, the reaction mixture was concentrated in vacuum. The oily residue was washed with Hexane:DCM (1:4) and the solvent concentrated in vacuum to give 2-nitro-6-(piperidin-2-ylmethoxy)benzonitrile hydrochloride (0.982 g, 116%). MS 262 (MH+).
