Procedure

3 g of aluminium/nickel alloy are added to a mixture of 3 g of the compound obtained in step A of Example 1 and 40 ml of 75% formic acid, and the mixture is refluxed for 2 hours. The insoluble material is filtered off by suction while hot and washed with MeOH, and the filtrate is concentrated under vacuum. The residue is taken up in chloroform, the insoluble material is filtered off by suction and washed with an MeOH/chloroform mixture, and the filtrate is concentrated under vacuum. The residue is taken up in chloroform and filtered, the filtrate is washed with saturated NaHCO3 solution and with saturated NaCl solution and dried over Na2SO4, and the solvent is evaporated off under vacuum. 2.4 g of the expected product are obtained.
