To a solution of 3-(4-chloro-7H-pyrrolo[2,3-d]pyrimidin-5-yl)benzonitrile (C14) (100 mg, 0.393 mmol) and (2S)-2-methylmorpholine (54 mg, 0.53 mmol) in n-butanol (20 mL) was added N,N-diisopropylethylamine (152 mg, 1.18 mol), and the reaction mixture was heated at 100° C. for 18 hours. The reaction mixture was then concentrated in vacuo; purification via preparative HPLC (Column: Phenomenex Gemini C18, 8 μm; Mobile phase A: ammonia in water, pH 10; Mobile phase B: acetonitrile; Gradient: 27% to 47% B) provided the product as a white solid. Yield: 17.5 mg, 54.8 μmol, 14%. LCMS m/z 320.2 [M+H+]. 1H NMR (400 MHz, CDCl3) δ 10.71 (br s, 1H), 8.53 (br s, 1H), 7.73-7.89 (m, 2H), 7.51-7.69 (m, 2H), 7.28 (s, 1H, assumed; partially obscured by solvent peak), 3.56-3.77 (m, 3H), 3.39-3.54 (m, 2H), 2.86-2.98 (m, 1H), 2.53-2.65 (m, 1H), 0.93-1.03 (m, 3H).
