Procedure

A solution of N-((trans-2-aminocyclohexyl)methyl)-2-(5-chloro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoropyrimidin-4-amine, 14f, (0.050 g, 0.077 mmol) in THF was treated with LiOH (0.5 mL, 1.0M) at 60° C. After 5 min, at 120° C., the solution was diluted with EtOAc, and washed with brine, filtered and concentrated in vacuo. Preparative HPLC provided the desired compound, 555, as a racemic mixture of trans isomers (12 mg, 33% yield).
