実験手順
To a solution of 6 g of N-[3-(hydroxymethyl)phenyl]-N-[[4-(tetradecyloxy)phenyl]methyl]acetamide in 100 ml of tetrahydrofuran is added 1.56 g of triethylamine and 1.76 g of methanesulfonyl chloride followed by stirring at ambient temperature for 1 hour. Added 11.14 g of lithium bromide and continued stirring for an additional hour. The mixture is poured into water and extracted with ether. The organic layer is washed with a solution of saturated sodium bicarbonate and brine then dried and evaporated to a residue which is crystallized from petroleum ether to give 6.6 g of the desired product as a white solid, m.p. 56°-58° C.
