Into a mixture of 3-(2-cyanomethyl-3-oxo-2,3-dihydropyridazin-6-yl)-2-phenylpyrazolo[1,5-a]pyridine (2.0 g) and triethylamine (1.02 ml) in pyridine (10 ml) was introduced hydrogen sulfide at 50° C. for 6 hours. The mixture was poured into water. The resulting solid was collected by filtration to give 3-(3-oxo-2-thiocarbamoylmethyl-2,3-dihydropyridazin-6-yl)-2-phenylpyrazolo[1,5-a]pyridine (2.18 g).
