The downstream synthesis method of this compound is introduced below.
General procedures for the preparation of l,l-difluoro-4-isocyanocyclohexane F. p HCOOEt F-?^| O PPh3 p ” tauAlpha ” ^^N^H ” v ,N. H NC Step A: Tert-but l 4-hydrox cyclohexylcarbamate. To a solution of 4-aminocyclohexanol (23 g, 0.2 mol) and Et3N (60 g, 0.6 mol) in THF (230 mL) was added (Boc)20 (87 g, 0.4 mol). The resulting solution was stirred at room temperature overnight. The solvent was removed under reduced pressure and the residue was extracted with EtOAc (3 x 200 mL). The combined organic layers were washed with water (2 x 200 mL) and brine (200 mL), dried over anhydrous Na2S04 and concentrated. The residue was purified by column chromatography on silica gel using DCM/ MeOH (V:V, 20: 1) to afford the desired product as a white solid. MS: 216.2 (M+l)+.
According to the analysis of related databases, 6850-65-3, the application of this compound in the production field has become more and more popular.
