実験手順

Into a reaction vessel were charged 6.00 parts by weight of (3R)-1,1,3-trimethyl-4-aminoindane (optical purity of 96.5% ee) and 1.62 parts by weight of 5% palladium-carbon (STD-type, manufactured by N. E. Chemcat Corporation), thereby obtaining a mixture. The reaction vessel was sealed, the gas in the reaction vessel was replaced with nitrogen, and then the mixture was stirred at 200° C. for 7.5 hours to obtain a reaction mixture. Thereafter, the obtained reaction mixture was cooled and filtered. The obtained solid was washed with 20 parts by weight of 2-propanol. The washing liquid recovered after washing and the filtrate obtained by filtration were combined. The combined mixture was concentrated under reduced pressure to obtain 5.06 parts by weight of 1,1,3-trimethyl-4-aminoindane. The obtained 1,1,3-trimethyl-4-aminoindane had an optical purity of 3.3% ee and a recovery rate of 84.3%.
