Dimethylformamide → HCID 22599797, compound

Participants

Reaction Steps

In 2 ml of N,N-dimethylformamide were dissolved 153 mg of 4-(2-butynyloxy)-6-(ethylamino)pyrimidine and 67 mg of allyl chloride, to which 40 mg of sodium hydride (60% in oil) was added, followed by stirring at room temperature for 3 hours. Then, ice water was added to the reaction mixture, which was extracted with ethyl acetate. The organic layer was washed twice with an aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated. The residue was subjected to preparative silica gel thin layer chromatography to give 157 mg of 4-(2-butynyloxy)-6-(N-ethyl-N-allylamino)pyrimidine (the present compound (110)).
