Reaction Steps
A mixture of 4-[(5,6-dichloro-pyridazin-4-ylamino)-methyl]-piperidine-1-carboxylic acid benzyl ester (EXAMPLE 65, 2.00 g, 5.06 mmol), Pd/C (10%, 0.20 g) in absolute ethanol (15 mL) was vigorously stirred under 1 atm H2 provided by a H2 balloon for 7 h. Filtered and concentrated, the reaction gave 4-[(Pyridazin-4-ylamino)-methyl]-piperidine. M.S.(M+1): 193.25
