Potassium Carbonate → 4-(morpholin-4-yl)-5-(1H-pyrazol-4-yl)-7H-pyrrolo[2,3-d]pyrimidine, formate salt

Participants

Reaction Steps

To a solution of [4-(morpholin-4-yl)-5-(1H-pyrazol-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]methanol (C21) (from the previous step, 0.10 g, ≦0.32 mmol) in acetonitrile (10 mL) was added potassium carbonate (0.34 g, 2.5 mmol) and the reaction mixture was stirred at room temperature for 30 minutes. The mixture was filtered and the filter cake was washed with ethyl acetate (3×20 mL). The combined filtrates were concentrated in vacuo; purification via preparative HPLC (Column: DIKMA Diamonsil(2) C18, 5 μm; Mobile phase A: 0.225% formic acid in water; Mobile phase B: acetonitrile; Gradient: 0% to 17% B) afforded the product as a pale solid. Yield: 36 mg, 0.11 mmol, 34% over 2 steps. LCMS m/z 271.2 [M+H+]. 1H NMR (400 MHz, CDCl3) δ 10.72 (brs, 1H), 8.47 (s, 1H), 7.78 (s, 2H), 7.19 (s, 1H), 3.60-3.67 (m, 4H), 3.41-3.48 (m, 4H).
