Reaction Steps

Treat a solution of tert-butyl 1-(6-(4-fluorophenyl)-4,5-dimethylpyridazin-3-yl)piperidin-4-yl(methyl)carbamate (1.04 g, 2.51 mmol) in 1,4-dioxane (10 mL) with 4 M HCl in 1,4-dioxane (15.0 mL). Stir the resulting mixture at ambient temperature for 2 h. Concentrate the reaction mixture under reduced pressure. Dissolve the residue in MeOH, and pour onto an SCX column (Varian, 10 g). Rinse the column with MeOH and CH2Cl2, and elute the product with a 1:1 mixture of CH2Cl2 and 2 M NH3/MeOH. Concentrate under reduced pressure to afford the title compound as an off-white solid (784 mg, 99%). ES/MS m/z 315.2 (M+1).
