Reaction Conditions

Reaction Steps

2-Fluorobenzonitrile (10.0 g, 82.8 mmol) was dissolved in acetonitrile (100 ml), and 40% aqueous methylamine solution (200 ml) was added thereto, followed by stirring at 60° C. overnight. 40% aqueous methylamine solution (100 ml) was further added thereto, followed by stirring at 60° C. for 9 hours. The reaction mixture was concentrated under reduced pressure, then water was added to the resulting residue, the mixture was extracted with chloroform. After the organic layer was dried (over anhydrous magnesium sulfate), the drying agent was filtered off, and the organic layer was concentrated under reduced pressure. The resulting oily substances were purified by silica gel column chromatography (the substances were eluted with an increasing concentration of chloroform from chloroform/hexane=1/2 to chloroform/hexane=1/1) to give the title compound (5.38 g, 49%).
