実験手順

This reaction was carried out under similar conditions to those described above in preparation of 6-chloro-4-(5-(4-hydroxy-4-methylpiperidin-1-yl)pyridin-2-ylamino)-2-methyl-pyridazin-3(2H)-one. (1R,5S)-3-methyl-8-(6-nitropyridin-3-yl)-3,8-diazabicyclo[3.2.1]octane (500 mg, 2.01 mmol) in methanol (15 ml) was hydrogenated at 50 psi with 10% Pd/C (42.9 mg, 40.3 umol) overnight. The catalyst was filtered off and the resultant filtrate was concentrated in vacuo to afford 5-(3-methyl-3,8-diazabicyclo[3.2.1]octan-8-yl)pyridin-2-amine. The product was carried to next reaction without further purification.
