Cyanoacetic acid → HCID 71015768, compound

Participants

Reaction Steps

Into a 50 mL round-bottom flask, was placed a solution of 3-[4-(2-fluorophenoxy)phenyl]-1-((2R)-pyrrolidin-2-ylmethyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (100 mg, 0.25 mmol, 1.00 equiv) in dichloromethane (10 mL), 1-[(1H-imidazol-1-yl)carbonyl]-1H-imidazole (80 mg, 0.49 mmol, 1.25 equiv), and 2-cyanoacetic acid (50 mg, 0.59 mmol, 3.80 equiv). The resulting solution was stirred for 1 h at room temperature and then concentrated under vacuum. The residue was loaded onto a silica gel column with dichloromethane/methanol (100:1; 50:1) to give 0.05 g (43%) of 3-[(2R)-2-([4-amino-3-[4-(2-fluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)pyrrolidin-1-yl]-3-oxopropanenitrile as alight yellow solid.
