Procedure

To a stirred solution of 2-amino-1,3,4-thiadiazol (0.84 g, 8.0 mmol) in pyridine (5 ml) was added 2-naphthoyl chloride (1.9 g, 10 mmol). The resulting mixture was stirred at reflux temperature for 15 min. cooled and quenched with water (100 ml). The precipitate was filtered off, washed with water (2×10 ml) and heptane (2×10 ml) and dried in vacuo affording 0.80 g (38%) of the title compound as a solid.
