1083224-23-0, 5-(2,4-Difluorophenyl)isoxazole-3-carboxylic acid is a Isoxazoles compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: To a solution of rac-(3R*,4R*)-4-amino-1-cyclohexyl-piperidine-3-carboxylic acid methyl ester 1.01 b (2.64 g, 10.4 mmol) in DMF (56.7 mL) at RT is added 5-(2,4-difluorophenyl)isoxazole- 3-carboxylic Acid (2.42 g, 10.4 mmol). DIPEA (5.83 mL, 33.4 mmol) is then added followed by HATU (4.16 g, 10.9 mmol). The reaction mixture is stirred overnight (17 h). The reaction mixture is concentrated, dissolved in DCM (300 mL) and treated with aq. sat. NaHC03 (225 mL). The organic layer is dried over MgS04 and evaporated. The crude residue is purified by prep. LC-MS under basic conditions (method E). The title compound is obtained as white powder; LC-MS method D tR = 1.15 min; [M+H]+ = 448.19., 1083224-23-0
As the paragraph descriping shows that 1083224-23-0 is playing an increasingly important role.
