910251-11-5, name is Potassium trifluoro(methoxymethyl)borate, belongs to ethers-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of Potassium trifluoro(methoxymethyl)borate
Under an argon atmosphere a mixture of 70 mg of tert-butyl 10-bromo-8-cyclopropyl-3,4,7,8-tetrahydro-1H-[1,4]diazepino[6,7,1-ij]quinoline-2(6H)-carboxylate (0.172 mmol, 1.00 eq) from step 8.2, 52.2 mg of potassium trifluoro (2-methoxymethyl)borate (0.344 mmol, 2.00 eq), 168 mg of cesium carbonate (0.516 mmol, 3.00 eq), 1.43 mg of Pd(OAc)2 (0.006 mmol, 0.04 eq) and 5.73 mg of X-Phos (0.012 mmol, 0.07 eq) in degassed dioxane (4 mL) and water (0.5 mL) was heated in a microwave at 130 C. for 40 h. Then the mixture was extracted with DCM and the organic phase was washed with water and dried over MgSO4, filtrated and solvent was evaporated to yield the title compound. ESI-MS: m/z (%): 373.30 (100, [M+H]+).
The synthetic route of 910251-11-5 has been constantly updated, and we look forward to future research findings.
