Reaction Steps

To a solution of 4-(hydroxymethyl)-2-naphthalenecarbonitrile (200 mg) in dry DCE (5 mL), CBr4 (542.8 mg) and (Ph)3P were added, the resulting mixture was stirred at r.t. for 40 min and then quenched with 40 mL of water. The aqueous phase washed with DCM (3×40 mL). The combined organic extracts were dried, concentrated, and purified by flash chromatography (CH/AcOEt from 8:2 to 1:1) to give the title compound (216 mg) as a white foam.
