Reaction Steps

2,3-Diaminotoluene (6.09 g, 49.8 mmol) and tetraethoxymethane (25 mL, 119 mmol) were mixed, and the mixture was stirred at 130° C. for 16 hr. The mixture was cooled to room temperature, diluted with ethyl acetate, washed with brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=70/30) to give the title compound (6.89 g, 78%).
