Tetrabutylammonium Fluoride Trihydrate → HCID 17874146, Verbindung

4-tert-Butyldimethylsilyloxymethyl-2-methylaminopyrimidine (40 mg, 0.16 mmol, Reference Compound No. 6-1) was dissolved in tetrahydrofuran (3.0 mL), then a solution of tetrabutylammonium fluoride trihydrate (55 mg, 0.17 mmol) in tetrahydrofuran (3.0 mL) was added thereto, and the mixture was stirred for 40 minutes at room temperature. The reaction mixture was concentrated under reduced pressure. The residue was suspended into 25% methanol-chloroform solution, and the mixture was filtered with silica gel (2.0 g). The filtrate was concentrated under reduced pressure to give 60 mg of the mixture of the title Reference Compound and tetrabutylammonium fluoride as a brown oil.
