Versuchsvorschrift
Thiobenzamide (447 mg, 3.26 mmol) was added under nitrogen to a solution of (2-bromo-1-(6-methoxy-2-naphthyl)ethanone (906 mg, 3.25 mmol), prepared in the previous step, in 25 mL of absolute ethanol at approximately 70° C. After the addition the reaction was refluxed for 2 h. The solid was collected by filtration, rinsed with absolute ethanol and dried under reduced pressure to give 4-(6-methoxy-2-naphthyl)-2-phenyl-1,3-thiazole (909 mg, 88%) as a white solid, mp 191-193° C. Elemental Analysis for C20H15NOS Calc'd: C, 75.68; H, 4.76; N, 4.41. Found: C, 75.37; H, 4.65; N, 4.31.
