Procedure

A mixture of formic acid (0.463 g) and N,N-dimethylacetamide (1 drop) was added to a solution of chlorosulfonyl isocyanate (1.31 g) in DCM (9 mL), and heated to reflux for 3 h. The resulting solution was added to a solution of 4-[2-Amino-4-chloro-7-(4-methoxy-3,5-dimethyl-pyridin-2-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl]-but-3-yn-1-ol (see example 2) (200 mg) in DMA (10 mL) and stirred at rt for 30 mm. Work-up and reverse-phase preparative HPLC gave the title compound, as a solid. HPLC Rt=4.96 mm.
