Reaction Steps
2.8 g of sodium hydride as a 60% dispersion in oil are added in small portions at RT to a solution of 13.35 g of 3,4-dichlorophenylacetonitrile in 100 ml of THF and the reaction mixture is stirred for 3 hours at RT. It is cooled to -20° C., a solution of 16 g of 2-(3-bromopropoxy)tetrahydropyran in 30 ml of THF is added dropwise and the reaction mixture is stirred for 3 hours while the temperature is allowed to rise to RT. It is concentrated under vacuum, the residue is extracted with ether, the organic phase is washed with water, with a buffer solution of pH 4 and with water and dried over MgSO4 and the solvent is evaporated off under vacuum. The residue is chromatographed on silica using a toluene/AcOEt mixture (100/3; v/v) as the eluent to give 11 g of the expected product.
