실험 절차

HCl (g) was bubbled through a solution of 4-allyl-1-(tert-butoxycarbonyl)piperidine-4-carboxylic acid [Jiang et al. (2004) Bioorg. Med. Chem. Lett. 14, 3675-3678] (6.50 g, 24.1 mmol,) in MeOH (200 mL). The solution was heated at reflux for 16 h and then concentrated in vacuo to give the title compound as the hydrochloride salt. MS: m/z=184(M+1).
