Dimethylformamide dimethyl acetal → C20H17N3O3S

Participants

Reaction Steps

N,N-Dimethylformamide dimethylacetal (620 μl) was added at room temperature to a tetrahydrofuran (THF) solution (8.5 ml) of 3-(1-benzenesulfonyl-1H-indol-2-yl)-3-oxo-propionitrile (1.0 g, 3.08 mmol), and stirred for ten minutes. The reaction mixture was then concentrated under reduced pressure to give crude 2-(1-benzenesulfonyl-1H-indole-2-carbonyl)-3-dimethylamino-acrylonitrile as yellow amorphous material. The obtained crude product was used in subsequent reactions without purification.
