The downstream synthesis method of this compound is introduced below.
To a solution of N-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)methanesulfonamide (0.875 g, 4.18 mmol) in DMF (25 mL) was added 60% NaH in mineral oil (0.193 g, 4.83 mmol). After 10 minutes, methyl 2,6-dichloropyrimidine-4-carboxylate (0.871 g, 4.21 mmol) was added. After stirring for 30 minutes, the reaction mixture was diluted into 100 mL water and extracted three times with 50 mL EtOAc. The combined organic layers were washed once with 25 mL brine, dried over MgSO4,filtered, and evaporated to a residue. The residue was chromatographed over silica gel with 30-60% EtOAc in hexanes. The product fractions were concentrated in vacuo. After sitting overnight a crystalline solid formed. The solid was decanted and dried under vacuum to give methyl 2-chloro-6-(N-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)methylsulfonamido)pyrimidine-4-carboxylate as a cream-colored powder (0.911 g, 2.40 mmol, 57% yield). LC/MS: m/z= 380.2 [M+H]+.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 6299-85-0, Methyl 2,6-dichloropyrimidine-4-carboxylate.
