Water → ethyl 2-[N-ethyl-N-(3,5-di-tert-butylphenyl)amino]pyrimidine-5-carboxylate

Participants

Reaction Steps

Ethyl 2-[N-(3,5-di-tert-butylphenyl)amino]pyrimidine-5-carboxylate (50 mg) was dissolved in dry DMF (2 ml), and the solution was added with a suspension of NaH (45 mg) in DMF (1 ml). The mixture was then added with ethyl iodide (0.3 ml) and stirred. After the disappearance of the materials was observed with TLC, the reaction mixture was poured into water, and extracted with CH2Cl2. The organic layer was dried over Na2SO4, and the solvent was evaporated. The residue was purified by silica gel flash column chromatography (n-hexane: AcOEt=10:1) to obtain white crystals of ethyl 2-[N-ethyl-N-(3,5-di-tert-butylphenyl)amino]pyrimidine-5-carboxylate (53 mg, 99%).
