실험 절차
4-[5-amino-6-[5-[4-(bromomethyl)phenyl]-1,3,4-oxadiazol-2-yl]pyrazin-2-yl]-N,N-dimethyl-benzamide (70 mg, 0.1460 mmol) was treated with methylamine (2 mL of 33% w/w solution in ethanol), and the resulting mixture stirred heated at 100° C. for 10 min. The reaction mixture was cooled to room temperature and filtered. The filtrate was collected and purified by reverse phase preparative HPLC [Waters Sunfire C18, 10 μM, 100 Å column, gradient 10%-95% B (solvent A: 0.05% TFA in water; solvent B: CH3CN) over 16 minutes at 25 mL/min]. The product fractions were passed through a carbonate cartridge eluting with MeOH/ CH2Cl2. The eluent was concentrated in vacuo and the solid triturated with acetonitrile to give the product as a yellow solid (11.4 mg, 19% yield); 1H NMR (400 MHz, DMSO) d 2.30 (s, 3H), 2.98-3.02 (m, 6H), 3.77 (s, 2H), 7.55 (d, 2H), 7.61 (d, 2H), 7.78 (br s, 2H), 8.11 (d, 2H), 8.17 (d, 2H) and 8.98 (s, 1H) ppm; MS (ES+) 430.31
