Into a 10-mL sealed tube was placed (1S)-1-(1-phenyl-1H-1,3-benzodiazol-2-yl)ethan-1-amine from Example 4 (300 mg, 1.26 mmol, 1.00 equiv), 4-chlorothieno[2,3-d]pyrimidine (250 mg, 1.47 mmol, 1.16 equiv), N-ethyl-N-isopropylpropan-2-amine (322 mg) and BuOH (5 mL). The resulting solution was stirred for 1 overnight at 120° C. and concentrated under vacuum. The residue was applied onto a silica gel column eluted with ethyl acetate/petroleum ether (0:100-80:20) to afford 260 mg (55%) of 143 as a light yellow solid. LC-MS (ES, m/z): 372 [M+H]+. 1H-NMR (300 MHz, CD3OD, ppm): δ 8.19 (s, 1H), 7.70 (d, 1H), 7.68-7.08 (m, 10H), 5.74-5.67 (m, 1H), 1.73 (d, 3H)
