Procedure

To a stirred suspension of 3-naphthalen-2-yl-acrylic acid hydrazide (1.0 g, 4.71 mmol, prepared as described in example 5) and triethylamine (0.64 g, 6.28 mmol) in dry tetrahydrofuran (15 ml) was added carbonyl diimidazole (1.02 g, 6.28 mmol) at 0° C. The reaction mixture was stirred at room temperature for 1 h. The resulting reaction mixture was evaporated in vacuo and to the residue was added water (25 ml). The precipitate was filtered off and washed with water (2×10 ml) and diethyl ether (2×10 ml) and recrystallised from ethyl acetate (100 ml) affording after drying In vacuo at 50° C. 0.5 g (45%) of the title compound as a solid.
