実験手順
1.18 g (54 mmol, 3 eq) of lithium borohydride are added to a solution of 6.9 g of methyl 3-benzyloxy-4-iodobenzoate in 30 ml of tetrahydrofuran. The reaction medium is heated at 60° C. for 12 hours and then hydrolyzed with ammonium chloride solution and extracted with ethyl acetate. The organic phases are combined and the solvents are evaporated off. 6.5 g of (3-benzyloxy-4-iodophenyl)methanol in oil form are used in the following reaction without further purification.
