Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 13788-84-6, name is 3-Methyl-4-phenyl-1H-pyrazole, This compound has unique chemical properties. The synthetic route is as follows., category: pyrazoles-derivatives
Example 4(2R)-N-hvdroxy-2-methyl-4-(3-methyl-4-phenyl-1 H-pyrazol-1-yl)-2-Step A: ethyl (2R)-2-methyl-4-(3-methyl-4-phenyl-1 H-pyrazol-1 -yl)-2-(methylsulfonvDbutanoateTo a solution of the 3-methyl-4-phenylpyrazole (400 mg, 2.53 mmol, 1 eq) in THF (25 mL) was added cesium carbonate (2.52 g, 7.70 mmol, 3 eq) and (R)-ethyl 4-bromo-2-methyl-2-(methylsulfonyl)butanoate (950 mg, 3.31 mmol, 1 .3 eq). The resulting suspension was heated to 70 C and stirred overnight. The reaction was filtered through celite, and the filter pad was washed with ethyl acetate (2x 100 mL). Combined filtrates were concentrated and the crude material was purified on a Analogix SF15-24g column using an eluant of ethyl acetate in heptane (0-80%) to give ethyl (2R)-2-methyl-4-(3-methyl-4-phenyl-1 H-pyrazol-1 -yl)-2- (methylsulfonyl)butanoate (178 mg, 19.3%). LC-MS M+H+ 365.1
