Procedure

0.107 g of sodium hydroxide in 1.36 ml of water and 0.51 ml of tetrahydrofuran are cooled to 0° C. 0.52 g of 2-amino-2-adamantanecarboxylic acid is added in a single portion, and 0.53 g of 1-(1-naphthyl)-5-(2,6-dimethoxyphenyl)-3-pyrazolecarbonyl chloride, dissolved in 3 ml of tetrahydrofuran, is then added dropwise. The mixture is left for 10 minutes, and the same amount of the above acid chloride, in 3 ml of tetrahydrofuran, is added again; simultaneously, 1.32 ml of 2N sodium hydroxide are added. The reaction mixture is left for 4 days at room temperature; successively, ice-cold water is added and concentrated hydrochloric acid is added to pH 1, and the precipitate is filtered off. The crystals are washed with diisopropyl ether.
