Reaction Steps

2.33 g of 4,5-dimethoxy-2-nitro-benzonitrile was added to 15 ml of toluene, 0.28 g of dibutyltinoxide and 2.58 g of trimethylsilyl azide was added thereto, and the mixture was stirred at 100° C. for 16 hours. The reaction mixture was distilled under a reduced pressure to remove the solvent, and the resulting solid was washed with 250 ml of dichloromethane to obtain 2.0 g of the title compound as a grey solid (yield 71%).
