Abstract

114,680. Newton, P. A., (Farbenfabriken vorm F. Bayer & Co.). Apcil 23, 1917. Bromdiethylacetylurethanes of N - acyl p - aminophenols are prepared by the reaction of bromdiethylacetylisocyanate (described in Specification 13433/13) on the acyl - p - aminophenols, or by the reaction of bromdiethylacetyl halides on the urethanes of the acyl - p - aminophenols. According to an example, p - acetylaminophenol in acetone suspension is treated with bromdiethylacetylisocyanate, giving the bromdiethylacetylurethane of p - acetylaminophenol; the same compound is obtained by reaction of p - aeetylaminophenolurethane with bromdiethylacethyl chloride in presence of dimethylaniline; the bromdiethylacetylurethane of p - oxyphenylurea also is described. The products are suitable for medicinal use as nervines and sedatives. Urethanes of acyl - p - aminophenols are prepared by heating guaiacolurethane with, say, p - acetylaminophenol.
