Procedure
A solution of N-(9-fluorenylmethoxycarbonyloxy)succinimide (4.4 g; 14.0 mmol) in 1,4-dioxane (40 mL) was added dropwise to a solution of trans-4-(aminomethyl)cyclohexanecarboxylic acid (2.0 g; 12.7 mmol) in 10% Na2CO3 (30 mL) cooled to 0° C. The mixture was then allowed to warm to ambient temperature and after 1 h stirring at room temperature was treated with 1 N HCl (32 mL) until the final pH was 2. The resulting solution was extracted with n-BuOH (100 mL); the volatiles were removed and the crude residue was purified by flash chromatography to give D as a white solid (1.6 g; 4.2 mmol). Yield 33%.
