Procedure
p-Hydroxybenzaldehyde (122 g, 1 mole), ethyl bromoacetate (167 g, 1 mole), potassium carborate (138 g, 1 mole) and acetone (500 ml) were united, stirred and refluxed for 3 hours. The reaction mixture was poured into crushed ice (2 kg). The solid that separates was removed by filtrations, washed with water, dried and recrystallized from ethanol to give 157 g of product, m.p. 41°-42° C.
