Potassium Phosphate, Tribasic → 1-(benzothiazol-6-yl)-3-(1-((2-(trimethylsilyl)-ethoxy)methyl)-1H-pyrrolo [2,3-b]pyridin-5-yl)imidazolidin-2-one

Participants

Reaction Steps

1-Benzothiazol-6-yl-imidazolidin-2-one (I-84b: 0.2 g, 0.9 mmol) was reacted with 5-bromo-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrrolo[2,3-b]pyridine (I-187a: 0.32 g, 1.0 mmol), 1,4-dioxane (15 mL), copper iodide (0.052 g, 0.2 mmol), trans N,N′-dimethyl-cyclohexane-1,2-diamine (0.038 g, 0.27 mmol) and potassium phosphate (0.65 g, 2.2 mmol) to afford the crude product. Purification by column chromatography on silica gel (1.5% methanol in DCM) afforded 0.22 g of the product (52.3% yield).
