Trifluoroacetic acid → HCID 11347930, compound

Participants

Reaction Steps

2-(2-Amino-pyrimidin-4-yl)-1,5,6,7-tetrahydro-pyrrolo[3,2-c]pyridin-4-one (140 mg, 0.61 mmol), trifluoroacetic acid (565 μl, 7.33 mmol), and cyclohexanecarbaldehyde (151 μl, 1.25 mmol) were mixed in DMF (10 ml). Sodium triacetoxyborohydride (390 mg, 1.84 mmol) was added to the above solution and the reaction mixture stirred at room temperature under N2 for 20 h. Additional cyclohexanecarbaldehyde (151 μl, 1.25 mmol) and sodium triacetoxyborohydride (390 mg, 1.84 mmol) were added and the reaction mixture was stirred 20 hours longer. The reaction was quenched with 0.33N NaOH (50 ml), and the product was extracted with DCM (50 ml). The DCM extract was dried (MgSO4), and the solvent was evaporated. The residue was purified by flash chromatography (DCM-MeOH, 95:5) to give the product as a beige solid (80 mg, 40% yield).
