実験手順

A suspension of 15.8 g of 3-nitro-5,6,7,8-tetrahydroquinoline [synthesized according to the method as described in Bull. Chem. Soc. Jpn. Vol. 63 (1990), 2820] and 1.6 g of 5% palladium carbon in 300 ml of methanol is hydrogenerated at ordinary temperature under atmospheric pressure. The catalyst is filtered off, and the filtrate is concentrated in vacuo to remove the solvent. The resultant crude product is recrystallized from methylene chloride-isopropyl ether to give 12.76 g of the titled compound 1. Yield: 97%
