Allylamine → 2,4,7-Triallylaminothieno[3,2-d]pyrimidine

Participants

Reaction Steps

120 mg (0.37 mmol) of 2,4-diallylamino-7-bromothieno[3,2-d]pyrimidine, 337 mg (5.9 mmol) of allylamine, 56 mg (0.41 mmol) of potassium carbonate and 1 mg of copper were heated in a sealed tube at 180° C. for 5 hours. After completion of the reaction, the reaction mixture was allowed to resume room temperature, followed by distilling off excess allylamine under reduced pressure. The residue was purified by silica gel chromatography (eluent: ethyl acetate-hexane=1/8) to give 81 mg (yield: 72.9%) of the title compound.
