Procedure

A stirred solution of 34.2 g (217.5 mmol) of trans 4-aminomethylcyclohexanecarboxylic acid (Aldrich) in 217 mL of 2M aq. NaOH and 217 mL of dioxane was cooled to 15° C. To this solution was added 25 mL (235 mmol) of allyl chloroformate (Aldrich) in a slow stream. After the addition, the cold bath was removed, and the solution was stirred overnight at ambient temperature. The reaction mixture was poured slowly into a rapidly stirred mixture of 1L of 1M aq. citric acid and ice. The resulting mixture was stirred for 0.5 h and the precipitate collected by filtration, washed with water, and dried to a constant weight of 49.3 g (94%) of the title compound as a colorless solid.
