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).
用一种简单、高效、高产的工艺生产杂质少、质量好的 1-烷氧羰基-3-苯基丙基衍生物,该工艺包括催化还原 1-烷氧羰基-3-氧代-3-苯基丙基衍生物。1- 烷氧羰基-3-苯基-丙基衍生物是通过在醇或含有醇的溶剂中,在浓度为 0.4 至 0.5 N 的强酸存在下进行催化还原而得到的,强酸的量以 1 个当量的 1- 烷氧羰基-3-氧代-3-苯基丙基衍生物(1 摩尔)为基准,至少为 3 个当量。
