실험 절차

5-(8-(((trans)-4-Methoxycyclohexyl)methyl)-7-oxo-5,6,7,8-tetrahydropyrazino[2,3-b]pyrazin-2-yl)-4-methylpicolinamide. 5-(8-(((trans)-4-Methoxycyclohexyl)methyl)-7-oxo-5,6,7,8-tetrahydropyrazino[2,3-b]pyrazin-2-yl)-4-methylpicolinonitrile (0.607 g, 1.55 mmol), trifluoroacetic acid (2.0 mL, 26.0 mmol) and sulfuric acid (0.5 mL, 9.38 mmol) were combined and heated at 65° C. for 1 h. Reaction pH was adjusted to 10 with sodium carbonate and the resulting solution was extracted with ethyl acetate (3×15 mL). Organic layers were collected, dried over magnesium sulfate, concentrated and purified using reverse-phase preparatory HPLC (10-100% acetonitrile+0.1% TFA in H2O+0.1% TFA, over 30 min). Clean fractions were combined and condensed under reduced pressure and dried under high vacuum to afford the title compound as a yellow solid (0.425 g, 1.04 mmol, 67% yield). MS (ESI) m/z 411.5 [M+1]+.
