PROCESS FOR THE PREPARATION OF 1-ALKOXYCARBONYL-3-PHENYLPROPYL DERIVATIVES |
摘要 |
To produce an 1-alkoxycarbonyl-3-phenylpropyl derivative having little amount of impurities and good quality by a simple, efficient and highly productive process which comprises catalytically reducing an 1-alkoxycarbonyl-3-oxo-3-phenylpropyl derivative. 1-Alkoxycarbonyl-3-phenyl-propyl derivative is provided and obtained by catalytic redution being carried out in an alcohol or a solvent containing the alcohol in the presence of a strong acid having a concentration of 0.4 to 0.5 N, the amount of the strong acid being at least 3 equivalents based on one equivalent of the 1-alkoxycarbonyl-3-oxo-3-phenylpropyl derivative (1 mole).
