Reaction Conditions

Reaction Steps

A suspension of 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (5.0 g, 19.15 mmol) in tetrahydrofuran (100 mL) was treated with tert-butyl 3-hydroxy-1-pyrrolidinecarboxylate (5.38 g, 28.73 mmol) and triphenylphosphine (7.53 g, 28.73 mmol). The reaction mixture was cooled to 0° C. on an ice bath. Diethylazodicarboxyate (5.0 g, 28.73 mmol) was slowly added to the reaction mixture. The solvent was removed under reduced pressure after 6 days. The crude oil was used directly in the subsequent reaction without further analysis.
