Synthetic Route of 1235036-15-3, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1235036-15-3, name is tert-Butyl 3-bromo-6-chloropicolinate, molecular formula is C10H11BrClNO2, molecular weight is 292.56, as common compound, the synthetic route is as follows.
To a solution of tert-butyl 3-bromo-6-chloropicolinate (3.06 g) in tetrahydrofuran (50 mL) and water (20 mL) was added Example 1.14.1 (4.45 g), 1,3,5,7-tetramethyl-8-tetradecyl-2,4,6-trioxa-8-phosphaadamantane (0.732 g), Pd2(dba)3 (0.479 g), and K3PO4 (11 g). The mixture was stirred at reflux overnight and concentrated. The residue was dissolved in ethyl acetate (500 mL) and washed with water and brine. The organic layer was dried over Na2SO4, filtered, and concentrated. The residue was purified by flash chromatography, eluting with a gradient of 20-40% ethyl acetate in dichloromethane, to provide the title compound. MS (ESI) m/e 530.23 (M+H)+.
Statistics shows that 1235036-15-3 is playing an increasingly important role. we look forward to future research findings about tert-Butyl 3-bromo-6-chloropicolinate.
