Potassium Carbonate → 4-(2-{1-[1-(4-Chloro-phenyl)-cyclobutyl]-3,4-dihydro-isoquinolin-7-yloxy}-acetyl)-piperazine-1-carboxylic acid tert-butyl ester

Participants

Reaction Steps

1-[1-(4-chlorophenyl)cyclobutyl]-3,4-dihydroisoquinolin-7-ol (example 82) (400 mg, 1.18 mmol) and 4-(2-chloro-acetyl)-piperazine-1-carboxylic acid tert-butyl ester (404 mg, 1.54 mmol) were dissolved in N,N-dimethyl-formamide (10 ml). After addition of potassium carbonate (355 mg, 2.57 mmol) the mixture was stirred for 2 h under reflux. The solvent was removed and the residue (690 mg) was used in the next step without further purification.
