Reaction Steps

855.5 mg of sodium hydride (as a 60% w/w dispersion in mineral oil) were added to a solution of 2.83 g of 4-nitrophenol in 30 ml of dimethylformamide cooled in an ice-water bath. The resulting mixture was stirred at the same temperature for 5 minutes, after which a solution of 4.88 g of 2-bromomethylbenzothiazole in 25 ml of dimethylformamide was added thereto. The temperature of the resulting mixture was elevated to room temperature, and the mixture was then stirred at this temperature for 4 hours. At the end of this time the reaction mixture was cooled in an ice-water bath and 100 ml of water was added to said reaction mixture resulting in the precipitation of a crystalline solid which was filtered off, washed with water and then further washed with hexane. The resulting crude crystalline solid was purified by column chromatography through silica gel using a 10:1 by volume mixture of hexane and ethyl acetate, to give 4.99 g (yield 86%) of the title compound having a melting point of 189° to 191° C.
