Procedure

Into a 25-mL round-bottom flask was placed a solution of (S)-1-(1-phenyl-1H-benzo[d]imidazol-2-yl)ethanamine from Example 4 (238 mg, 1.00 mmol, 1.00 equiv) in n-BuOH (5 mL), 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (153 mg, 1.00 mmol, 1.00 equiv) and N-ethyl-N-isopropylpropan-2-amine (0.5 mL). The resulting solution was stirred overnight at 130° C. and concentrated under vacuum. The crude product was purified by applying onto a C18 Column (water/acetonitrile) to afford 150 mg (41%) of 148 as a white solid. LC-MS (ES, m/z): 355 [M+H]+. H-NMR (300 MHz, CD3OD, ppm): δ 7.97 (s, 1H), 7.69 (d, 1H), 7.48 (m, 5H), 7.25 (m, 2H), 7.11 (m, 2H), 6.58 (d, 1H), 5.65 (q, 1H), 1.71 (d, 3H)
