実験手順

10 Grams of (2,3-dihydro-7-hydroxy-1-hydroxyimino-4-methyl-1H-indene-6-yl)methylaminocarbonylmethylpyridinium chloride, 200 ml of acetic acid and 1.0 g of platinum oxide were subjected to catalytic hydrogenation under 3 atmospheric hydrogen gas pressure at room temperature for 8 hours. After the hydrogenation was completed, the catalyst was removed by filtration, and the filtrate was concentrated to dryness under a reduced pressure. The residue thus obtained was dissolved in 100 ml of methanol and under ice-cooled condition, a methanol solution saturated with hydrogen chloride gas was added thereto so as to adjust the pH of the solution to about pH 1, then the said solution was concentrated to dryness under a reduced pressure. The residue thus obtained was recrystallzed from ethanol-diethyl ether to obtain 4.8 g of 1-amino-2,3-dihydro-7-hydroxy-4-methyl-6-piperidinylacetylaminomethyl-1H-indene dihydrochloride. Colorless powdery crystals. Melting point: 146° C. (decomposed).
