| titleOfInvention | A carbamic acid ester having a sedative effect and methods for the preparation thereof |
| abstract | The invention comprises phenyl-isopropyl-methyl carbamate and the preparation thereof by the following methods: (1) reacting phenyl-isopropyl-carbinol with cyanic acid, e.g. by heating with alkali metal cyanates in neutral solvents such as methylene chloride in the presence of acids such as trichloracetic acid; (2) reacting the carbinol at low temperatures with urea chloride or at elevated temperatures with urea, with or without the addition of heavy metal salts, e.g. zinc acetate, or with urea salts; (3) reacting the carbinol with urethanes such as ethyl urethane, with or without the addition of reaction accelerators such as sodium alcoholate, by heating; or (4) converting the carbinol to the chlorocarbonic acid ester thereof by means of phosgene, e.g. in a solvent such as toluene, and then reacting this ester with ammonia. Examples are given. |
