실험 절차

A solution of 0.20 g (0.87 mmol) of (rac)-3-hydroxymethyl-3-methyl-piperidine-1-carboxylic acid tert-butyl ester was dissolved in 5 ml of CH2Cl2, treated at 0° C. with a solution of HCl in dioxane (2.18 ml, 4 M in dioxane) and stirred for 2 h at RT. The reaction was then concentrated to dryness and re-evaporated with toluene to afford the title product (0.17 g, quant.) as white solid. MS: 130.1 (MH+)
