YieldReaction ConditionsOperation in experiment
In N-methyl-acetamide; mineral oil; (Step A-1) 53.2 mg of sodium hydride (as a 60% w/w dispersion in mineral oil) were added to a solution of 200.0 mg of 4-acetamido-3-methylphenol in 10 ml of dimethylformamide cooled in an ice-water bath. The resulting mixture was stirred at the same temperature for 5 minutes, and then 307.9 mg of <strong>[73101-74-3]2-<strong>[73101-74-3]bromomethylbenzoxazole</strong></strong> ?prepared as described in Example 28(a) above! were added. The temperature of the resulting mixture was elevated to room temperature and the mixture was stirred for 30 minutes. At the end of this time, the temperature of the reaction mixture was elevated to 50 C. and the mixture was stirred for a further 1.5 hours. At the end of this time, a saturated aqueous ammonium chloride solution was added to the reaction mixture and the resulting mixture was extracted with ethyl acetate. The resulting extract was washed consecutively with water and a saturated aqueous sodium chloride solution and then dried over anhydrous sodium sulfate. The solvent was then removed by evaporation under reduced pressure to give a crude crystalline solid which was purified by column chromatography through silica gel using a 3:1 by volume mixture of ethyl acetate and hexane as the eluent, to give 218.5 mg (yield 61%) of the title compound as a solid having a melting point of 160 C. Nuclear Magnetic Resonance Spectrum, (200 MHz, CDCl3) delta ppm: 7.78-7.74 (1H, multiplet); 7.58-7.51 (2H, multiplet); 7.39-7.34 (1H, multiplet); 6.92-6.84 (3H, multiplet); 5.30 (2H, singlet); 2.24 (3H, singlet); 2.18 (3H, singlet).
