| titleOfInvention | Method for producing urethane compound |
| abstract | (57) [Summary] [Purpose] The amino group of amino acid ester hydrochloride has di-t- After producing a urethane compound having a structure in which an amino group is protected by reacting a dicarbonate such as butyl dicarbonate, the desired urethane compound is isolated from the reaction solution by a simple means. [Structure] Amino acid ester hydrochloride, L-serine methyl ester hydrochloride and the general formula (1) (However, R 1 is an alkyl group, an alkenyl group, or an aralkyl group.) In a method for producing a urethane compound by reacting with a dicarbonate, for example, di-t-butyl dicarbonate, an inorganic base, for example, In the presence of potassium carbonate, the reaction is carried out in an organic solvent, for example, chloroform, in which an inorganic salt produced by neutralization of the inorganic base during the reaction is difficult to dissolve and a urethane compound produced can be dissolved. |
