A further 5.15 g of nitroacetone and 3.85 g of ammonium acetate are added and the mixture is boiled for 24 hours, and 5.15 g of nitroacetone and 3.85 g of ammonium acetate are added and the mixture is boiled for 24 hours. It is cooled and concentrated, the residue is taken up in ethyl acetate, and the solution is extracted by shaking twice with water, dried and concentrated.
