Reaction Steps

Ethyl 7-(7-((isopropylamino)methyl)-2,3-di-p-tolyldi-p-tolyl-5H-pyrrolo[2,3-b]pyrazin-5-yl)heptanoate (Example 4.1) (53 mg, 0.101 mmol) in EtOH (1 ml) was treated with 2M NaOH (0.151 ml, 0.302 mmol) and stirred at RT for 16 hours. The solvent was removed under reduced pressure and the crude product was dissolved in water and the pH was adjusted to pH 1 using 2M HCl. The mixture was extracted with DCM (×3) and the combined organic extracts were concentrated under reduced pressure to afford an orange solid. The solid was suspended in diethyl ether, sonicated and then filtered, rinsing the filter-cake with diethyl ether (×3). The resultant solid was dried under atmosphere to afford the titled compound as an orange solid.
