Versuchsvorschrift

To a solution of (S)-1-(6-fluoro-1-phenyl-1H-benzoimidazol-2-yl)ethylamine dihydrochloride (30.7 g, 93.7 mmol) in IPA (300 mL) was added 6-chloro-9-(tetrahydropyran-2-yl)-9H-purine (26.9 g, 112.5 mmol) and DIPEA (48 mL, 281.2 mmol) and the reaction mixture heated at 80° C. for 16 h. The reaction mixture was concentrated in vacuo and the residue dissolved in EtOAc (600 mL). The solution was washed with water and the organic fraction separated. The organic fraction was washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, eluting with 0-10% methanol in EtOAc) to yield the title compound as a yellow oil (30 g, 70%) 1H NMR 400 MHz (CDCl3) δ 8.25 (1H, s), 7.96 (1H, s), 7.70 (1H, qn, J=4.1 Hz), 7.37-7.58 (5H, m), 6.98-6.82 (1H, m), 6.52-6.66 (1H, m), 5.60-5.77 (2H, m), 4.12-4.19 (1H, m), 3.76 (1H, td, J 11.3, 2.5 Hz), 1.91-2.13 (4H, m), 1.68-1.84 (2H, m), 1.60-1.68 (3H, m)
