Reaction Steps

To a solution of ethyl 2,3-diaminobenzoate (3.0 g) in methanol (60 mL) was added 1 N hydrochloric acid (0.6 mL) and benzaldehyde (1.7 mL), and the mixture was stirred at room temperature for 1 hour. After evaporation of the solvent under a reduced pressure, to the solution of the obtained residue in dichloromethane was added silica gel. The solvent was evaporated under a reduced pressure, and the resulting residue was heated at 100° C. for 1 hour. By purifying the reaction mixture by a silica gel column chromatography (eluent:hexane/ethyl acetate), the title compound was obtained as crystal (1.8 g).
