Reaktionsschritte

5-Amino-2-methylbenzoxazole (14 8 g, 0.100 mol) and 2,6-lutidine (12.0 g, 0.111 mol) were combined with 100 mL of tetrahydrofuran (THF) and the solution was cooled to 3° C. in an ice-bath under nitrogen. 2-Furoyl chloride (13.7 g, 0.105 mol) in 20 mL of THF was added dropwise so as to keep the temperature below 10° C. After addition the ice-bath was removed and after stirring for 1 hour the mixture was poured into 300 mL of water. The solid was collected and washed with water and dried. This afforded 21.1 g (87% yield) of product; m.p. 156°-158° C.
