A mixture of C-(3-phenylbenzo[b]thiophen-2-yl)methylamine from Example 26 (230 mg, 0.961 mmol), 6-chloro-9H-purine (278 mg, 1.80 mmol) and DIPEA (0.34 mL, 1.92 mmol) in n-butanol (10 mL) was heated at 100° C. for 20 h. After cooling to RT, volatiles were removed under reduced pressure and the resulting residue was purified by column chromatography (Si—PCC, gradient 0-10% MeOH in DCM) and then sonicated in diethyl ether. Further purification by column chromatography (Si—PCC, gradient 0-5% MeOH in DCM) afforded 165 as a white solid (132 mg, 38%). LCMS: RT 4.22 min [M+H]+ 358.1. 1H NMR (DMSO, 400 MHz): δ 12.96 (1H, s), 8.40 (1H, s), 8.23 (1H, s), 8.14 (1H, s), 7.94-7.85 (1H, m), 7.63-7.54 (4H, m), 7.51-7.43 (2H, m), 7.38-7.29 (2H, m), 4.94 (2H, s)
