Procedure
Methyl chloroformate (54 uL, 0.70 mmol) was added to a mixture of 3-amino-3-cyclohexylpropanoic acid (100.0 mg, 0.5840 mmol) (Key Organics/Bionet, Cat. #7T-0112) and potassium carbonate (160 mg, 1.2 mmol) in water (2.0 mL, 110 mmol) and tetrahydrofuran (2.0 mL, 25 mmol). After stirring at r.t. for 10 min, the mixture was extracted with ether to remove impurity. The aqueous layer was adjusted to pH=2 with HCl, and extracted with ethyl acetate (3×10 mL). The combined organic layers were dried over MgSO4, filtered and concentrated under reduced pressure to afford the desired product (130 mg, 97%). Analytic LCMS (M+H)+: m/z=230.1.
