Sodium Bicarbonate → HCID 20675274, compound

Participants

Reaction Steps

In a stream of nitrogen, sodium bis(trimethylsilyl)amide (1.0 M in THF, 8.47 ml, 8.47 mmols) was added, under cooling with ice, to a tetrahydrofuran solution (30 ml) of Compound 36 (1.86 g, 2.42 mmols), and the mixture was stirred for 1 hour at room temperature. A saturated sodium bicarbonate solution (14 ml) was added to the reaction mixture, and then the solvent was distilled off under reduced pressure. After water was added to the residue, the mixture was extracted with chloroform. The organic phase was washed with a saturated sodium chloride solution, and then dried over sodium sulfate. The solvents were distilled off under reduced pressure, and the resulting crude product was purified by silica gel column chromatography (AcOEt-hexane, 2:3) to obtain a white powder, Compound 37 (1.42 g, 2.37 mmols, 98%).
