Sodium hydride → Propane-1-sulfonic acid [2-amino-6-(2,6-dichlorophenyl)-pyrido[2,3-d]pyrimidin-7-yl]-amide

Participants

Reaction Steps

To a slurry of 1.00 g of 2,7-diamino-6-(2,6-dichlorophenyl)-pyrido[2,3-d]pyrimidine from Example 1 in 15 mL of DMF was added 0.15 g sodium hydride (60% in mineral oil) portionwise and the mixture stirred for 1 hour. Propanesulfonyl chloride (0.39 mL) is added dropwise, and the reaction mixture stirred at ambient temperature for 16 hours. The reaction mixture is filtered to remove a small amount of insoluble material and the filtrate evaporated in vacuo. The product is purified by medium pressure liquid chromatography (MPLC) using silica gel and eluting with a gradient of CHCl3 :EtOAc (2:1) to CHCl3 :EtOAc (1:1) to afford the title compound.
