Procedure

To a solution of 4-chloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidine (4.0 g, 14.34 mmol, 1.0 eq), (S)-tert-butyl 2-(hydroxymethyl)pyrrolidine-1-carboxylate (4.04 g, 20.08 mmol, 1.4 eq), and PPh3 (7.5 g, 28.68 mmol, 2.0 eq) in dry THF (30 mL), DIAD (5.80 g, 28.68 mmol, 2.0 eq) was added dropwise at 0° C. The mixture was stirred at RT for 5 h. The reaction mixture was concentrated and purified by silica gel chromatography (eluted with PE:EtOAc 1:1) to afford (S)-2-(4-chloro-5-iodo-pyrrolo[2,3-d]pyrimidin-7-ylmethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (5.1 g, 77% in yield).
