Reaction Steps

To a solution of (4aRS,9bRS)-4a-methyl-2,3,4,4a,5,9b-hexahydro-1H-indeno[1,2-b]pyridine (140 mg) in 1,2-dichloroethane (3 ml) were added acetic acid (0.214 ml) and sodium triacetoxyborohydride (1.1 g), followed by heating and stirring at 70° C. for 3 hours. The reaction solution was basified by adding a 1 M aqueous sodium hydroxide solution, extracted with chloroform, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to obtain (4aRS,9bRS)-1-ethyl-4a-methyl-2,3,4,4a,5,9b-hexahydro-1H-indeno[1,2-b]pyridine (105 mg) as an oily substance. This was made into a hydrochloride by a conventional method, washed with ethyl acetate, and collected by filtration to obtain (4aRS,9bRS)-1-ethyl-4a-methyl-2,3,4,4a,5,9b-hexahydro-1H-indeno[1,2-b]pyridine hydrochloride (108 mg) as a colorless powder.
