Reaction Steps

Allyl bromide (1.13 ml, 9.35 mmol) was added dropwise over 10 minutes to a heterogeneous mixture of 2-(1H-benzimidazol-2-yl)benzoxazole (second step of Example 1) (2 g, 8.5 mmol) and potassium carbonate (1.29 g) in 10 ml of DMF heated to 70° C. The heating was continued at 70° C. for 4 hours. The reaction mixture was cooled and poured into water. The precipitate obtained was filtered off, washed with water and dried. 2.3 g (yield: 96%) of 2-(1-allyl-1H-benzimidazol-2-yl)-benzoxazole were obtained in the form of a beige-colored powder.
