Reaction Steps

Triethyl amine (10 ml, 72.2 mmol) was added to a solution of 2,4-dihydroxybenzophenone (1) (5.4 g, 23.3 mmol) in THF (50 ml) and the solution cooled to 0° C. Ethyl chloroformate (6.9 ml, 72.2 mmol) was added slowly and the suspension stirrred for ˜30 mins at 0° C., and for ˜3 hrs at room temperature. Water (150 ml) was added and the mixture extracted with diethyl ether (150 ml). The extracts were washed with water (2×150 ml) and saturated aqueous sodium chloride solution (100 ml). The solution was dried over anhydrous magnesium sulphate and concentrated to give 4-benzyl-benzene-1,3-diol as a pale green gum, solidified on standing, (8.2 g).
