37924-85-9, A heterogeneous catalyst is a catalyst that is present in a different phase than the reactants. Such catalysts generally function by furnishing an active surface upon which a reaction can occur. 37924-85-9, name is 3-(Bromomethyl)benzo[d]isoxazole, introduce a new downstream synthesis route as follows.

General procedure: To NaOMe (25% soln, 0.5 mL, 2.2 mmol) in MeOH (5 mL) was added thiosemicarbazide 9 (200 mg, 2.2 mmol). Diethyloxalate (0.3 mL, 2.2 mmol) was then added dropwise. The mixture was heated at 65 C for 2 h and then cooled to rt. 1-(Bromomethyl)-4-chlorobenzene (500 mg, 2.4 mmol) was added in one portion; stirring was continued at rt for 3 h and then heated overnight at 50 C. The reaction mixture was concentrated. The residue was dissolved in EtOAc (40 mL), washed with water (20 mL), and brine (20 mL). The organic phase was dried over Na2SO4, concentrated and purified by silica gel column chromatography (EtOAc w/ 0.2% HOAc). The product was triturated in Et2O to afford 59 mg of 6g as a light yellow solid (10% yield)

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 37924-85-9, We look forward to the emergence of more reaction modes in the future.
