실험 절차

A solution of 2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine-8-carbaldehyde (250 mg, 0.64 mmol), 3,3-dimethylpiperazin-2-one (100 mg, 0.78 mmol) and molecular sieves (4 Å, powdered, 1 g) in DCE (15 mL) was stirred at ambient temperature for 4 h. Sodium triacetoxyborohydride (204 mg, 0.96 mmol) was added and the mixture stirred for 16 h, then loaded onto an Isolute® SCX-2 cartridge (10 g). The cartridge was then washed with methanol and the desired product was subsequently eluted using 2 M NH3 in MeOH. The product was collected and concentrated in vacuo. The resultant residue was purified by flash chromatography (Si—PPC, DCM:MeOH, 100:0 to 98:2 to 95:5) to afford 649 as a yellow solid (34 mg, 11%). LCMS (method I): RT=3.12 min, M+H+=504. 1H NMR (CDCl3, 400 MHz) δ 8.02 (m, 1 H), 7.79 (m, 1 H), 7.30 (m, 2 H), 5.75 (bs, 1 H), 4.34 (m, 4 H), 3.94 (s, 2 H), 3.92 (s, 3 H), 3.87 (m, 4 H), 3.38 (q, J=7.4 Hz, 2 H), 3.23 (m, 2 H), 2.80 (m, 2 H), 1.54 (s, 6 H) and, 1.47 (t, J=7.4 Hz, 3 H)
