Tetrabutylammonium Fluoride → HCID 58213470, compound

Participants

Reaction Steps

A solution of 8-((tert-butyldimethylsilyloxy)methyl)-3-chlorobenzo[f][1,7]naphthyridin-5-amine (from the previous step) (1.0 eq.) and TBAF (1.1 eq.) in THF was stiffed at ambient temperature overnight. The reaction was quenched with saturated NaHCO3. The two phases were separated, and the aqueous layer was extracted twice with Et2O. The combined organic layers were washed with brine, dried over anhydrous MgSO4, and concentrated en vacuo. The crude material was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-5% MeOH/DCM to give (5-amino-3-chlorobenzo[f][1,7]naphthyridin-8-yl)methanol as a white solid.
