Trimethylsilyl isocyanate → 4-{3-[5-Chloro-4-(4-cyclopropylcarbamoylbenzo[b]thiophen-2-yl)-pyrimidin-2-ylamino]-propyl}-piperidine-1-carboxylic acid amide

Participants

Reaction Steps

Trimethylsilyl isocyanate (26 mg, 0.22 mmol) is added to a stirred suspension of 2-[5-chloro-2-(3-piperidin-4-yl-propylamino)-pyrimidin-4-yl]-benzo[b]thiophene-4-carboxylic acid cyclopropylamide (50 mg, 0.11 mmol) in DMF (1 mL) and stirred for 2 hours. The mixture is diluted with ethyl acetate (1 mL) then filtered to give the title compound as a yellow solid (43 mg). ES+(m/z) 513 (35Cl) and 515 (37Cl) [M+H].
