4-Fluoro-2-(1-methylethoxy)benzenamine → N-(3-(Dimethylamino)propyl)-4-(4-fluoro-2-iso-propoxyphenylamino)-5-methylthieno[2,3-d]pyrimidine-6-sulfonamide

Participants

Reaction Steps

4-Fluoro-2-iso-propoxyaniline (0.049 g, 0.28 mmol) and 4-chloro-N-(3-(dimethylamino)propyl)-5-methylthieno[2,3-d]pyrimidine-6-sulfonamide hydrochloride salt (0.1 g, 0.28 mmol) were heated at 70° C. in anhydrous 1,4-dioxane (1.5 mL) for 4 hours. The solution was cooled to ambient temperature and diluted with water (2.0 mL) and adjusted to pH 9 (4:1 water/ammonium hydroxide solution). The precipitate was collected, washed with water and diethyl ether to yield the title compound as beige solid (0.039 g, 28%).
