Reaction Steps

A mixture of 4.9 g (0.015 mole) of 6-[(phenylmethoxy)methyl]-4-(phenylmethyl)-2-morpholinemethanol and 2.84 g (0.016 mole) of 2-chloro-N,N-dipropylacetamide are dissolved in 100 ml of dry DMSO and the mixture stirred at room temperature under nitrogen. Slowly, 0.88 g of sodium hydride (0.0183 mole, 50% oil dispersion) is added to the DMSO mixture and the reaction allowed to stir at ambient temperature (22°). After stirring for 10 minutes, an exothermic reaction begins to take place and an ice-bath is used to maintain the reaction temperature below 30°. After stirring for 1/2 hour, the ice-bath is removed and the reaction allowed to stir at room temperature for 18 hours. The excess NaH is destroyed by adding 5 ml of methanol and the entire reaction mixture is then poured into 400 ml of water. The product is extracted and washed with 6×300 ml portions of water. The product is then extracted with 3×125 ml portions of chloroform. The CHCl3 extracts are combined and washed with 6×300 ml portions of water. The CHCl3 layer is separated and dried over anhydrous Na2SO4 overnight. The CHCl3 is removed in vacuo yielding the crude product as a dark oil. The resulting oil is purified on a neutral Alumina III column (200 g), eluting with 2% methanol/chloroform, yielding 4.6 g (69%) of the desired product, 2-[[6-[(phenylmethoxy)methyl]-4-(phenylmethyl)-2-morpholinyl]methoxy]-N,N-dipropylacetamide.
