Procedure

C-(3-Chloro-pyrazin-2-yl)-C-(2-phenyl-quinolin-7-yl)-methylamine (250 mg, 0.72 mmol) was dissolved in 4.0 mL of CH2Cl2 and DIPEA (139.8 mg, 1.08 mmol) and DMAP (8.8 mg, 0.07 mmol) were added. The reaction was cooled to 0° C. and acetyl chloride (68 mg, 0.87 mmol) was added to the homogenous reaction mixture. After 3 h the reaction was complete. Water was added and the organic layer was washed with NaHCO3 sat. aq. sol (1×), H2O and Brine. The organic layers where combined, dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified with silica gel column chromatography [Jones Flashmaster, 10 g cartridge, eluting with 2% MeOH: CH2Cl2] to yield a dark oil; 1H NMR (400 MHz, CDCl3) δ 2.08 (s, 3H), 6.80 (d, 1H, J=7.9 Hz), 7.26-7.23 (m, 4H), 7.70-7.92 (m, 4H), 8.09-8.11 (m, 2H), 8.17 (d, 1H, J=8.60 Hz), 8.37 (d, 1H, J=2.40 Hz), 8.57 (d, 1H, J=2.49 Hz); MS (ES+): 430.84 (M+1), 432.83 (M+3), 433.92 (M+4).
