Potassium hydroxy sulfite → 7-({3-[(Dimethylamino)carbonyl]phenyl}sulfonyl)-4-{[3-(methyloxy)phenyl]amino}-3-quinolinecarboxamide

Participants

Reaction Steps

Oxone (0.22 g) was added portionwise to a stirred solution of Example 575 (0.035 g) in N,N-dimethylformamide (4 ml). The mixture was stirred at room temperature under nitrogen for 24 h, a further portion of oxone (0.17 g) was added, and the mixture stirred for a further 5 h. The reaction was quenched with a solution of sodium sulphite (1.2 g) in water (15 ml), diluted with water (10 ml) and extracted with ethyl acetate (3×30 ml). The combined organic extracts were dried over magnesium sulphate and concentrated in vacuo to give the title compound as a buff solid (0.035 g).
