Procedure

To a cooled solution (0° C.) of [3-(2-methoxy-ethoxymethoxy)-phenyl]-methanol (212 mg, 1 mmol, example 72) in THF (3 mL) is added 60% NaH (80 mg, 2 mmol) and the mixture stirred 10 min. Added 2-picolyl chloride hydrochloride (164 mg, 1 mmol) and DMPU (0.8 mL), removed cold bath and let reaction mixture stir for 2 hrs. Quenched reaction with sat NH4Cl soln. and diluted with EtOAc. The organic layer is washed with brine, dried over MgSO4 and concentrated. The residue is purified by flash chromatography (silica, 70% ethyl acetate in hexanes) to give the title compound as a pale yellow oil. MS (ESI) 304 (M+H)+.
