Participants

Reaction Steps

Add CH2Cl2 (20 mL) and trifluoroacetic acid (20 mL) to tert-butyl-1-(4,5-dimethyl-6-(pyridine-4-yl)pyridazin-3-yl)piperidin-4-yl(methyl)carbamate (1.19 g, 2.99 mmol). Stir at ambient temperature for 3 d. Concentrate under reduced pressure to give a residue. Partition the residue between CH2Cl2 and 1 N NaOH. Separate the layers, and extract the aqueous layer twice with CH2Cl2. Combine the organic extracts, dry over Na2SO4, filter, and concentrate under reduced pressure to obtain the title compound (790 mg, 89%). ES/MS m/z 298.2 (M+1).
