実験手順

Combine methyl-piperidin-4-yl-carbamic acid tert-butyl ester (75 g, 349 mmol), 1-chloro-4-(4-fluoro-phenyl)-phthalazine (75 g, 289 mmol), and potassium carbonate (80 g, 579 mmol) in dimethyl sulfoxide (500 mL) and heat the mixture to 110° C. for 3 h. Cool the reaction to ambient temperature and pour the slurry into water (1.0 L). Collect the solids by filtration and dry in a vacuum oven for 3 days to provide the title compound as a white solid (120 g, 95%). ES/MS m/z 437.3 (M+1).
