Reaction Steps

The suspension of 2-methylsulfanyl-5-quinazolin-6-ylmethylene-thiazol-4-one (example 1c, 58 mg, 0.2 mmol), thiophene methyl amine (45.3 mg, 0.4 mmol) and diisopropylethylamine (DIEA) (70 uL, 0.4 mmol) in acetonitrile (1 mL) was heated to 145° C. by microwave for 20 min. After cooling to room temperature, the solid was collected by filtration, washed with a small amount of acetonitrile and dried. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 0%-5% methanol in methylene chloride in 30 min) afforded 5-[1-quinazolin-6-yl-meth-(Z)-ylidene]-2-[(thiophen-2-ylmethyl)-amino]-thiazol-4-one as a light yellow solid: LC-MS m/e 353 (MH+).
