Reaction Steps

A mixture of 3-(4-chlorophenyl)-5-(piperazin-1-yl)-1,2,4-thiadiazole (539 mg, 1.92 mmol), 2-bromo-4′-methoxyacetophenone (440 mg, 1.92 mmol) and DIPEA (744 mg, 1.01 ml, 5.76 mmol) in 10 mL EtOH was stirred for 2 h at RT. Another portion 2-bromo-4′-methoxyacetophenone (220 mg, 960 μmol) was added and stirring continued for 2 h. The reaction was filtered off and washed with MeOH (4×5 mL) and Et2O (2×5 mL). The filter cake was dried in vacuo at 50° C. to yield 526 mg (64%) of the title compound as white solid. MS (m/e): 429.2 (MH+).
