A solution of (1S)-1-(1-phenyl-1H-1,3-benzodiazol-2-yl)ethan-1-amine from Example 4 (150 mg, 0.62 mmol, 1.00 equiv, 98%), 6-chloro-8-methyl-9H-purine (150 mg, 0.87 mmol, 1.41 equiv) and ethylbis(propan-2-yl)amine (0.3 mL, 98%) in butan-1-ol (6 mL) was stirred overnight at 130° C. The resulting mixture was concentrated under vacuum. The residue was purified on a C18 column eluted with water/acetonitrile to give 75 mg (30%) of 158 as a white solid. LC-MS (ES, m/z) 370 [M+H]+. H-NMR (300 MHz CD3OD, ppm) δ 8.04 (s, 1H), 7.69 (d, 1H), 7.55 (m, 5H), 7.30 (m, 2H), 7.11 (d, 1H), 5.63 (s, 1H), 2.55 (s, 3H), 1.71 (d, 3H)
