Reaction Steps

A suspension of 1 g (3.5 mmol) of 6-bromo-4-chloro-7-methoxy-2-methyl-quinoline in 20 ml of EtOH was treated sequentially at RT and under stirring with 0.49 g (7 mmol) of pyrrolidine, 0.137 g (1.4 mmol) of pyridine and a catalytic amount of NaI. The mixture was then heated to reflux for 20 h, cooled to RT and concentrated in vacuo. The residue was applied to a silica gel column with CH2Cl2/MeOH (7:1) as eluent. Combinations of the purified fractions and concentration in vacuo gave 0.85 g (68.2%) of the 6-bromo-7-methoxy-2-methyl-4-pyrrolidin-1-yl-quinoline hydrochloride as light brown solid. ISP mass spectrum, m/e: 323.3 (M+1 calculated for C15H17BrN2O: 323).
