実験手順

A mixture of 9-methyl-2-(2-methylbenzoimidazol-1-yl)-6-morpholin-4-yl-9H-purine-8-carbaldehyde (100 mg, 0.26 mmol), (3-methylpyrrolidin-3-yl)pyrrolidin-1-ylmethanone (58 mg, 0.32 mmol), trimethoxyorthoformate (0.29 mL, 2.65 mmol) and acetic acid (15 μL, 0.26 mmol) in DCE (5 mL) was stirred at room temperature for 1 hour then sodium triacetoxyborohydride (90 mg, 0.42 mmol) was added. The reaction mixture was stirred at room temperature for 18 hours then diluted with MeOH and loaded onto an Isolute® SCX-2 cartridge (10 g). The cartridge was washed with MeOH and the desired product was eluted with 2M NH3 in MeOH. The solvents were removed and the residue was subjected to flash chromatography (Si—PCC, 0-20% MeOH in EtOAc) to give 396 as a white solid (107 mg, 76%). LCMS (Method G): RT 6.69 min; [M+H]+ 544. 1H NMR (400 MHz, CHCl3-d): δ 8.12-8.07 (m, 1 H); 7.74-7.70 (m, 1 H); 7.30-7.26 (m, 2 H); 4.35 (m, 4 H); 3.90 (s, 3 H); 3.87 (t, J=4.75 Hz, 5 H); 3.49 (m, 5 H); 2.96 (s, 3 H); 2.64 (s, 2 H); 2.46-2.37 (m, 2 H); 1.89 (m, 4 H); 1.81 (m, 2 H); 1.41 (s, 3 H).
