Reaction Steps

Diisopropyl azodicarboxylate (0.61 mL) is added to a solution of methyl 3-hydroxy-4-trifluoromethoxybenzoate (0.74 g), cyclopentanol (0.19 g) and triphenylphosphine (0.81 g) in tetrahydrofuran (10 mL) and the mixture is heated overnight at reflux. Solvent is evaporated off under reduced pressure and the resulting yellow oil is triturated with diethyl ether. The white solid thus formed is filtered off, and the filtrate is evaporated under reduced pressure and subjected to mplc, to give methyl 3-cyclopentyloxy-4-trifluoromethoxy-benzoate in the form of a pale yellow oil (0.6 g).
