29049-45-4, 6-Chloropyridazin-4-amine is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a stirred suspension of potassium tert-butoxide (3.90 g, 34.7 mmol) in 1,4-Dioxane (50 mL) was added a mixture of (,S)-(2,2-dimethyl-l,3-dioxolan-4-yl)methanol (2.75 g, 20.84 mmol) at 0 C and the reaction mixture was stirred at 25 C for 1 h. under Nitrogen atmosphere, then 6-chloropyridazin-4-amine (1.5 g, 1 1.58 mmol) was added to the reaction mixture and the resulted reaction mixture was stirred at 1 10 C for 16 h. (TLC System: Neat Ethyl acetate, Rf: 0.3). The reaction mixture was poured in to ice cold water (40 ml) and extracted with EtOAc (2×80 mL). The combined organic layer was washed with brine solution (50 mL), dried over anhydrous Na2S04, filtered and concentrated under reduced pressure to get crude compound. The crude material was purified by flash column chromatography (Neutral alumina, Eluent: 65% Ethyl acetate in Pet ether) to afford the desired product (,S)-6-((2,2-dimethyl-l,3-dioxolan-4-yl)methoxy)pyridazin-4-amine (1.0 g, 4.28 mmol, 37.0 % yield) as a white solid. LCMS (m/z): 226.20 [M+H]+.
29049-45-4, As the paragraph descriping shows that 29049-45-4 is playing an increasingly important role.
