1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 57929470, compound

Participants

Reaction Steps

EDCI (7.690 g, 40.26 mmol) and benzotriazole (4.796 g, 40.26 mmol) were added to a suspension of 4-cyclopentylamino-2-methylsulfanyl-pyrimidine-5-carboxylic acid (10.186 g, 40.26 mmol) in DCM (250 mL), at RT, and the reaction mixture was stirred for 1 h. The resulting mixture was washed 3 times with water; the combined aqueous extracts were extracted twice with DCM. The combined organic layers were dried over Na2SO4, filtered and evaporated under reduced pressure to give a crude oil. This material was triturated with hot tert-butyl methyl ether and the mixture was left to stand overnight. The white solid which formed was collected by filtration to give 7.698 g (54% yield) of benzotriazol-1-yl-(4-cyclopentylamino-2-methylsulfanyl-pyrimidin-5-yl)-methanone.
