| titleOfInvention |
A method for cleavage of ketamine racemates |
| abstract |
A process for the resolution of racemic 2- (o-chlorophenyl) -2-methylaminocyclohexanone in which 1/2-o-chlorophenyl / 2-methylaminocyclohexanone is reacted with an enantiomeric form of tartaric acid; tartaric acid-chlorophenyl / 2-methylaminocyclohexanone and 3 / tartaric acid salt of 2- (o-chlorophenyl) -2-methylaminocyclohexanone is reacted with alkali to isolate the 2- (o-chlorophenyl) -2-methylaminocyclohexanone isomer wherein step 1 and 2 are carried out in water or in a mixture of water and a C 1 -C 6 alcohol or in a mixture of water and ketone, ether or ester. |
