실험 절차

A mixture of 2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine-8-carbaldehyde (0.092 g, 0.234 mmol), 3-methyl-[1,3′]biazetidinyl-3-ol (0.040 g, 0.28 mmol) and 4 Å molecular sieves (0.25 g) in DCE (3 mL). The reaction mixture was stirred for 90 min at room temperature. Sodium triacetoxyborohydride (0.099 g, 0.47 mmol) was added and the reaction mixture was stirred for 18 h at room temperature. The suspension was filtered through Celite and the filtrate was concentrated in vacuo. The residue was purified by flash chromatography (Si—PPC, MeOH:DCM, gradient 0:100 to 10:90) to give 587 as a white solid (0.107 g, 89%). LCMS (Method I): RT=2.33 min, [M+H]+ 518.2 1H NMR (300 MHz, DMSO-d6): δ 8.03-7.99 (m, 1 H), 7.65-7.61 (m, 1 H), 7.27-7.22 (m, 2 H), 4.49-3.95 (m, 4 H), 3.84 (s, 2 H), 3.80-3.74 (m, 4 H),3.36-3.31 (s, 3 H), 3.31-3.20 (m, 6 H), 3.11-3.01 (m, 4 H), 2.98-2.93 (m, 2 H), 1.34 (m, 5 H)
