Versuchsvorschrift

According to GP1 tert-butyl 4-(2,4-dioxo-6-phenyl-1,4-dihydrothieno[3,2-d]pyrimidin-3(2H)-yl)piperidine-1-carboxylate (855 mg; compound B50) is reacted with 2-(chloromethyl)-4-methyl-1,3-thiazole (368 mg; compound D13) in the presence of potassium carbonate (276 mg) in DMF (15 ml). Using WU1 a solid is obtained which is purified by flash chromatography [silica gel, eluation gradient: DCM/MeOH, 100/0 to 95/5 (v/v)] to give the title compound as a solid.
