4-Amino-2-chloropyrimidine-5-carbonitrile → 4-Amino-5-cyano-2-{4-[N-(3-hydroxy-2,2-dimethylpropyl)sulphamoyl]anilino}pyrimidine

Participants

Reaction Steps

A solution of 4-amino-2-chloro-5-cyanopyrimidine (150 mg, 0.97 mmol), 4-[N-(3-hydroxy-2,2-dimethylpropyl)sulphamoyl]aniline (Method 4; 274 mg, 1.07 mmol) in NMP (5 ml) was heated at 120° C. for 24 hours. The mixture was allowed to cool, was diluted with water and extracted with ethyl acetate. The organic extracts were combined, dried and the solvent removed by evaporation, the residue was triturated with ether and the product collected by filtration to give the title compound (187 mg, 52%). NMR: 0.72 (s, 6H), 2.52 (d, 2H), 3.08 (d, 2H), 4.40 (t, 1H), 7.19 (t, 1H), 7.60 (s, 1H), 7.64 (d, 2H), 7.96 (d, 2H), 8.40 (s, 1H); m/z 375 (M−H)−.
