Here is a downstream synthesis route of the compound 153747-97-8.
[0951] A solution ofcompound 90b (125 g, 366 mmol) inDMF (1.30 L)was treatedwith, 4,4,4′,4′,5,5,5′,5′-octamethyl2,2′-bi(1,3,2-dioxaborolane) (186 g, 732 mmol), Pd(OAc) 2(4.09 g, 18.3 mmol), PPh3 (19.2 g, 73.2 mmol) and KOAc(108 g, 1.10 mol) under a nitrogen atmosphere. The resultingmixture was stirred overnight at 80 C. Upon cooling to roomtemperature, the solids were collected by filtration. The filtrate was concentratedunderreduced pressure, and the resultant residue was purified by flash colunm chromatography onsilica gel (EtOAc/petroleum ether (1 :50 v/v)) to obtain compound 90c as a white solid (80.0 g, 56% yield). Mass Spectrum (LCMS, ESI pos.): Calcd. for C20H32BN3 0 4 : 390.2(M+H). found 390.2.
According to the analysis of related databases, 153747-97-8, the application of this compound in the production field has become more and more popular.
