Versuchsvorschrift

n-Butyl-isobutyramide (2.06 g, 0.0144 m) in dry THF (20 ml) was stirred at room temperature during the dropwise addition of a 1.445 M solution of n-butyl lithium in hexane (10.0 ml., 0.01445 m). After the addition, the mixture was stirred for 5 minutes, and then 4,5-diphenyl-2-iodooxazole (Chemical Abstracts 65 7159h) (5.0 g, 0.0144 m) in dry THF (20 ml) was added dropwise. The mixture was stirred for 6 hours at room temperature and then hydrolysed with water. The solvent was removed in vacuo and the residue extracted with diethyl ether.
