Following the general procedure for the synthesis of acyloxyalkyl carbamates, D-serine (252 mg, 2.4 mmol) and (2,5-dioxoazolidinyloxycarbonyloxy)ethyl benzoate (614 mg, 2.0 mmol) were reacted to provide 410 mg (69% yield) the title compound (28) as a white powder after work-up and mass-guided preparative HPLC purification. 1H NMR (CDCl3, 400 MHz): δ=8.00 (m, 2H), 7.55 (m, 1H), 7.40 (m, 2H), 7.01 (m, 1H), 6.59 (br s, 1H), 6.21 (m, 1H), 4.39 (m, 1H), 4.02 (m, 1H), 3.86 (m, 1H), 1.60 (2d, 3H). MS (ESI) m/z 298.10 (M+H)+; 315.11 (M+NH4)+; 320.07 (M+Na)+.
