実験手順

Pyridine was added to a suspension of C-[2-Amino-6-(2,4-dimethylphenyl)-5-formyl-pyrimidin-4-ylsulphanyl]-N-cyclopropyl-methane sulphonamide in dichloromethane and the mixture cooled, ice/water. Trifluoroacetic anhydride was added and the mixture stirred for ˜2 hrs and heated under reflux for ˜24 hrs. The resulting dark red solution was allowed to cool and aqueous ammonia (0.880) added and the mixture stirred for ˜30 mins. Dichloromethane was added and the mixture washed with dilute hydrochloric acid, water and saturated aqueous sodium chloride solution. The solution was dried over anhydrous sodium sulphate and concentrated to a red/orange solid. The crude solid was purified by preparative HPLC.
