PREPARATION EXAMPLE 26 Preparation of 2-t-butyl-4-chloro-5-[{6-(2,2,2-trifluoroethoxy)-3-pyridyl}-methylthio]-3(2H)-pyridazinone (Compound No. 1055) In 40 ml of methanol were dissolved 2.2 g of 2-t-butyl-4,5-dichloro-3(2H)-pyridazinone and 2.4 g of 5-mercaptomethyl(2,2,2-trifluoro-ethoxy)-pyridine, and thereto was added 1.2 g of sodium carbonate. The reaction mixture was stirred overnight at room temperature and then poured into water. Then, procedures similar to those in Preparation Example 24 were conducted to obtain 3.6 g of 2-t-butyl-4-chloro-5-[{6-(2,2,2-trifluoroethoxy)-3-pyridyl}-methylthio]-3(2H)-pyridazinone, m.p. 109.0~110.0 C. NMR (CDCl3, delta, TMS): 1.61 (9H, s), 4.22 (2H, s), 4.73 (2H, q, J=9 Hz), 6.87 (1H, d, J=9 Hz), 7.62 (1H, s), 7.60~7.89 (1H, m), 8.15 (1H, d, J=2 Hz).
