1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 86615855, compound

Participants

Reaction Steps

A mixture of 500 mg of {1-[2-(4-chloro-2,5-difluorophenyl)thieno[3,2-d]pyrimidine-4-yl]piperidine-4-yl}acetic acid hydrochloride, 316 mg of ammonium chloride, 0.82 ml of triethylamine, 319 mg of HOBt, 452 mg of EDCI and 10 ml of DMF was stirred for 5 days at room temperature. 60 ml of water was added to the reaction mixture and after the precipitate was filtered and washed with water, it was dried at 50° C. under reduced pressure. The obtained solid was dissolved in 10 ml of THF and was added to 2 ml of 4M HCl-dioxane solution. The resultant was concentrated under reduced pressure to give a solid. This solid washed with ether to give 573 mg of 2-{1-[2-(4-chloro-2,5-difluorophenyl)thieno[3,2-d]pyrimidine-4-yl]piperidine-4-yl}acetamido hydrochloride.
