different alcohols, phenols, diols and this intermediate at room temperature with grinding and in solvent-free conditions undermicrowaveirradiation. The presence of various safe bases is shown to be effective in reducing the reaction times, increasing the yields and easing purification. The present method does not involve any hazardous phosgene.
