実験手順
A mixture of N-[4-(4-chloro-7-isopropylpyrrolo[2,3-d]pyrimidin-5-yl)phenyl]-benzenesulphonamide (0.34 g), concentrated ammonia (30 ml, SG 0.880) and 1,4-dioxane (30 ml) was heated with stirring at 120° C. in a pressure vessel for 16 hours. The mixture was allowed to cool to ambient temperature and the solvent was removed under reduced pressure to give a residue which was partitioned between water (40 ml) and ethyl acetate (40 ml). The organic layer was separated and the aqueous layer was further extracted with ethyl acetate (2×40 ml). The combined ethyl acetate extracts were washed, dried, filtered and evaporated to give a solid which was purified by flash column chromatography on silica using ethyl acetate/cyclohexane (8:2) as the mobile phase. Appropriate fractions were collected, combined and concentrated to give N-[4-(4-amino-7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)phenyl]benzenesulphonamide, m.p. 238-240° C.
