Procedure

Methyl 2-(5-(2,3-di-p-tolyldi-p-tolyl-5H-pyrrolo[2,3-b]pyrazin-6-yl)pentanamido)acetate (step 1) (17 mg, 0.036 mmol) in THF (1 ml) and water (0.5 ml) was treated with LiOH. monohydrate (8.12 mg, 0.108 mmol). After stirring at room temperature for 3 hours, the reaction mixture was treated with water (20 ml) and the pH adjusted to pH 2 using 2M HCl. The aqueous portion was extracted with DCM (×3) and the combined organic extracts were concentrated under reduced pressure. Purification by reverse phase (C18) chromatograpy eluting with 0-30% MeCN in water (0.1% TFA) afforded the titled compound;
