Steps:
4.2 Preparation of 2,5-bis [3-bromophenyl) -1,3,4-oxadiazole
3-bromobenzoyl chloride (1.7 ml, 12.9 mmol) was added in one portion to a solution of D1 (2.93 g, 13.O mmol) in 33 ml of anhydrous pyridine at a temperature of 120 ° C under a nitrogen atmosphere. The oil was stirred for 2 days.After cooling to room temperature, the mixture was poured into 300 mL of deionized water.The resulting solid was washed with water and ethanol and recrystallized from absolute ethanol to give a white solid (4.50 g, 11.8 mmol).
