Reaction Conditions

Reaction Steps

Lithium hydroxide monohydrate (4.08 g, 97.5 mmol) was added to methyl 2-(2-chloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-2-methylpropanoate (18.5 g, 48.7 mmol) (see Preparation 41) in THF (185 mL) and water (45 mL). The mixture was stirred at 60° C. for 3 hours then the reaction mixture volume was reduced to one third by evaporation in vacuo. The aqueous residue was acidified using aqueous HCl (2.0 M) then extracted with EtOAc (4×200 mL). The organic phase was evaporated in vacuo and the crude material was triturated with hexane (100 mL) to afford the title compound as a white solid in 90% yield, 16.0 g.
