Hydrochloric Acid → HCID 67247052, compound

Participants

Reaction Steps

Water (4.3 ml, 236 mmol) in DMF (20 ml) was added drop wise at room temperature with stirring to a mixture of acetic acid 3,5-diacetoxy-phenyl ester (refer Kawamoto. H. et. al. Synth. Commun. M, 531, 1996) (35 g, 139 mmol), NaH (5.66 g, 236 mmol) and benzyl chloride (19.16 ml, 166 mmol) in dry DMF (300 ml). The reaction mixture was stirred overnight (˜16 h), poured into chilled dil. aqueous HCl and extracted with CH2Cl2 to obtain the crude title compound which was purified using flash chromatography (silica ge, 20-50% CH2Cl2 in PE 60-80° C.). Yield, 12.5 g (30%), white solid; mp: 129-30° C.; MS (EI): 300 (M+), 258, 216, 91 (100%); analysis: C17H16O5 requires: C, 67.99; H, 5.37 found: C, 67.50; H, 5.40%.
