Procedure

8.2 g 3-Chloro-4-hydroxymethyl-1-phenyl-isoquinoline are suspended in 300 ml toluene and 16.2 g phosphorus tribromide are added thereto while cooling with ice. After a 10 hours' stirring at room temperature dimethylamine is introduced until an alcaline reaction occurs. The reaction mixture is concentrated and water is added to the residue. Extraction with acetic acid ester gives a yellow oil, that crystallizes slowly. Melting point 75° to 77° C. Hydrochloride: 244° to 246° C.
