Procedure

To a stirred solution of isopropyl chloroformate (2 g, 0.016 mol.) in 10 mL of DCM at 0° C. under nitrogen atmosphere was added pyridine (3.8 mL, 0.048 mol) and then ethylene glycol (2.7 mL, 3 eq). The progress of the reaction was monitored by thin layer chromatography (TLC). After stirring for 15 hrs at room temperature. After removing the solvent under reduce pressure, the residue was purified by silica gel column chromatography to give 2-hydroxyethyl isopropyl carbonate as a colorless oil (0.5 g, 42% yield). 1HNMR (400 MHz, CDCl3): δ 1.22 (t, J=7.2 Hz, 3H); 2.94 (sbroad, 1H); 3.78 (t, J=4.4 Hz, 2H); 4.18 (t, J=4.4 Hz, 2H); 4.07 (q, J=7.2H, 2H).
