Reaction Steps

Potassium carbonate (30 mg, 0.20 mmol) was added to 5-(5-(bromomethyl)thiophen-3-yl)-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde (25 mg, 0.07 mmol) dissolved in DMF (0.7 mL). Pyrrolidine (6 μL, 0.07 mmol) was added and the reaction was heated to 50° C. for 1.25 h. Water (3 mL) was added and the orange precipitate was filtered and dried in vacuo to give 7-(cyclopropylamino)-5-(5-(pyrrolidin-1-ylmethyl)thiophen-3-yl)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde (13 mg, 54%) which was used without further purification. LCMS (ES): >85% pure, m/z 368 [M+1]+.
