Dimethylformamide → 2-Dimethylaminomethyl-9-methoxy-4H-thieno[2,3-c]isoquinolin-5-one

Participants

Reaction Steps

9-Methoxy-4H-thieno[2,3-c]isoquinolin-5-one (12.7 g; 54.9 mmol) and N,N-dimethylmethyleneammonium chloride (8.53 g; 91.14 mmol) were placed in a 0.5 L three neck round bottle flask under nitrogen atmosphere. Under stirring, DMF (75 mL) was added followed by acetonitrile (ACN) (190 mL) and the reaction mixture was placed into a preheated oil bath (90° C.). The reaction was complete after 1.5 hrs indicated by a worked up NMR sample.
