To a solution of 5-chloro-6-hydroxynaphthalene-2-carbonitrile (1.5 mmol) and K2CO3 (3 mmol) in acetone was added tert-butyl (2-bromoethyl)carbamate (2.1 mmol). The resulting mixture was heated at reflux overnight. After TLC control (n-hexane/ethyl acetate 65:35), solvent was evaporated in vacuo and the residue was dissolved in 15 mL of ethyl acetate and washed with water (3×5 mL), brine (10 mL) and dried over Na2SO4. The evaporation of solvent afforded tert-butyl {2-[(1-chloro-6-cyanonaphthalen-2-yl)oxy]ethyl}carbamate as a brown solid (81% yield) which was used without further purification.
