Application of 148017-28-1, A common heterocyclic compound, 148017-28-1, name is tert-Butyl sulfamoylcarbamate, molecular formula is C5H12N2O4S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a solution of {(1S,2S,4R)-2-{[tert-butyl(dimethyl)silyl]oxy}-4-[(6-{[(1R,2S)-2-methoxy-2,3-dihydro-1H-inden-1-yl]amino}pyrimidin-4-yl)oxy]cyclopentyl}methanol (105.3 mg, 0.0002168 mol), N-Boc-sulfonamide (58.9 mg, 0.000300 mol) and triphenylphosphine (85.3 mg, 0.000325 mol) in EtOAc (4.15 mL) under an atmosphere of nitrogen was added diethyl azodicarboxylate (51.9 muL, 0.000330 mol). The mixture was stirred for four hours. The solvent was removed and the orange residue was purified by flash chromatography (10 to 50% EtOAc/hexanes) to obtain 135.2 mg (94%) of the title compound.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
