Reaction Steps

N4-[2-(Methylthio)ethyl]quinoline-3,4-diamine (4.2 g, 19.2 mmol), trimethyl orthobutyrate (2.86 g, 19.2 mmol), pyridine hydrochloride (catalytic amount) and toluene were combined in a pressure vessel and heated at 140° C. for 1 hour. The reaction mixture was allowed to cool and then it was concentrated under reduced pressure to provide 4.9 g of 1-[2-(methylthio)ethyl]-2-propyl-1H-imidazo[4,5-c]quinoline.
