Diisopropylamine → 6-chloro-N-(4-(N-(2-methoxyethyl)sulfamoyl)-2-methylphenyl)pyrimidine-4-carboxamide

Participants

Reaction Steps

A solution of 4-(6-chloropyrimidine-4-carboxamido)-3-methylbenzene-1-sulfonyl chloride (Intermediate 30, 400 mg; 1.15 mmol) in THF (20 ml) was treated with 2-methoxyethanamine (125 mL; 1.4 mmol) and diisopropylamine (0.4 ml; 2.9 mmol). After stirring at RT for 18 hours the solvent was removed in vacuo and the residue redissolved in DCM and washed with water. The organic extracts were passed through a hydrophobic frit and the solvent removed in vacuo. The residue was purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of EtOAc. The title product was obtained as a white solid.
