반응 단계
To a solution of tert-butyl-2-hydroxy-2-methyl-cyclopentylcarbamate (25 g, 104.5 mmol) in dichloromethane (210 mL) is added hydrogen chloride in dioxane (156 mL, 6 mol, 4 M) and the reaction is stirred at room temperature for 3 h. The solvent is evaporated and the resulting material is dried under vacuum to a constant weight to obtain the title compound (20.4 g) as a dark brown oil which is used in the next step without further purification. GC-MS 115.1 (M+); GC-MS analysis shows a cis/trans mixture in about a 3/2 ratio.
