Procedure

Ethyl 4-aminobenzoate (8.25g) in a mixture of conc. hydrochloric acid (12.5ml) and water (12.5ml.) at 0° C was diazotised by the addition of sodium nitrite (3.45g). The solution of the diazo compound was added to benzyl alcohol (20g) at 35° C with stirring then stirred at this temperature for 3 hr. The reaction mixture was cooled and 4-ethoxycarbonylphenoxy phenyl methane isolated by extraction with ether, m.p. 45° C.
