Reaction Steps

4-(2-{1-[1-(4-Chloro-phenyl)-cyclobutyl]-3,4-dihydro-isoquinolin-7-yloxy}-acetyl)-piperazine-1-carboxylic acid tert-butyl ester (690 mg, 1.28 mmol) was dissolved in dichloro-methane. A 5 M solution of HCl in 2-propanol (5 mol) was added and the mixture was stirred for 14 h at RT. The solvent was removed and the residue (230 mg) was used in the next step without further purification.
