Procedure

The (3-amino-2-fluoro-phenyl)-(7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanone (39, 20.0 mg, 0.078 mmol) is further reacted, for example, by adding 0.5 mL of tetrahydrofuran, 50 μL of pyridine, and an appropriate sulfonyl chloride (e.g. ethanesulfonyl chloride 40, 0.078 mmol). The reaction vial is allowed to stir at room temperature or in an oil bath at 60° C. After 1-3 days, the solvents are removed under vacuum, the residue dissolved in 0.5 mL dimethyl sulfoxide, and the material purified by C18 reversed phase HPLC, eluting with 20-100% acetonitrile (with 0.1% trifluoroacetic acid) in water (with 0.1% trifluoroacetic acid) at a flow rate of 20 mL/min. Ethanesulfonic acid [2-fluoro-3-(7H-pyrrolo[2,3-d]pyrimidine-5-carbonyl)-phenyl]-amide (P-0036) was prepared by this protocol using ethanesulfonyl chloride 40 in step 4. MS (ESI) [M+H+]+=349.1.
