PREPARATION EXAMPLE 1 Preparation of 2-t-butyl-4-chloro-5-[4-(2-isopropylthioethoxy)-benzyloxy]-3(2H)-pyridazinone (Compound No. 310) In 15 ml of N,N-dimethylformamide were dissolved 1.2 g of 2-t-butyl-4,5-dichloro-3(2H)-pyridazinone and 1.2 g of p-(2-isopropylthioethoxy)benzyl alcohol, and then 0.31 g of powdery potassium hydroxide was added thereto. The resulting mixture was stirred overnight at room temperature, poured into water, extracted with diethyl ether, washed with water, dried over anhydrous sodium sulfate and then freed of the diethyl ether by distillation under reduced pressure. The resulting solid was recrystallized from n-hexane to obtain 1.2 g of the aimed compound, m.p. 82.0~84.5 C. 1 H-NMR (CDCl3, delta, TMS): 1.28 (3H, d, J=6.5 Hz), 1.62 (9H, s), 2.90 (2H, t, J=7.0 Hz), 2.90 (1H, dq, J=6.5 Hz), 4.12 (2H, t, J=7.0 Hz), 5.21 (2H, s), 6.85 (2H, d, J=8.4 Hz), 7.29 (2H, d, J=8.4 Hz), 7.69 (1H, s).
The synthetic route of 84956-71-8 has been constantly updated, and we look forward to future research findings.
