This compound was prepared from cyclohexyl 2-chloroacetate and Boc-Beta-Ala-OH by an analogous method to 3-tert-butoxycarbonylamino-propionic acid dipropylcarbamoylmethyl ester (Int. AA step 1). Cesium carbonate was used in place of potassium carbonate; 1H NMR (400 MHz, DMSO-d6) δ 6.83 (1H, br s), 4.76-4.70 (1H, m), 4.62 (2H, s), 3.20-3.12 (2H, m), 2.53 (2H, under DMSO peak), 1.28-1.72 (2H, m), 1.68-1.60 (2H, m), 1.53-1.18 (15H, m).
