1-Chloro-N,N-2-trimethylpropenylamine → HCID 67005722, compound

Participants

Reaction Steps

In an inert atmosphere, trans-4-(trifluoromethyl)cinnamic acid (34 mg, 0.156 mmol) was dissolved in DCM (3 mL) and 1-chloro-N,N,2-trimethylpropenylamine (24 mg, 0.182 mmol) was added at rt. The reaction mixture was stirred for 30 min followed by the addition of 1-(4-benzyl-piperazin-1-yl)-2-[(1H-indol-5-ylmethyl)-amino]-(S)-3-phenyl-propan-1-one (59 mg, 0.13 mmol). Stirring was continued at rt for 3 h. The solvents were evaporated under reduced pressure and the residue was directly purified by prep. HPLC to give 33 mg (39%) of N—[(S)-1-benzyl-2-(4-benzyl-piperazin-1-yl)-2-oxo-ethyl]-N-(1H-indol-5-ylmethyl)-3-(4-trifluoromethyl-phenyl)-acrylamide. LC-MS: tR=0.96 min; [M+H]+=651.24.
