Reaction Steps

26 g (85 mmol) 2-(3-chloropropoxy)-9H-thioxanthen-9-one is suspended in 140 mL acetonitrile. 66 g (73.2 mL, 0.85 mol) of a 40% solution of methyl amine in water was added and the mixture was heated to 60° C. After four hours, 1.3 g (8.5 mmol) sodium iodide and 20 mL of a 40% solution of methyl amine in water were added and the reaction was allowed to continue for 16 hours at 60° C. The precipitated compounds were isolated by filtration and washed three times with 100 mL acetonitrile. The pooled acetonitrile fractions were evaporated under reduced pressure. The crude 2-(3-methylaminopropoxy)thioxanthen-9-one was crystallized from 200 mL hexane, isolated by filtration and dried. 19 g of 2-(3-methylaminopropoxy)thioxanthen-9-one was isolated. 2-(3-methylaminopropoxy)thioxanthen-9-one was further purified by preparative column chromatography on a Prochrom LC80 column, using Kromasil C18 100A 10 mm as silica and methanol/1M ammonium acetate 68/32 as eluent at a flow rate of 150 mL per minute.
