Reaction Steps

To a solution of 16 g (76 mM) of 2-(4-chlorophenyl)- 4,4-dimethyl-4,5-dihydrooxazole in 60 ml of dry tetrahydrofuran at -78° C. under an inert atmosphere was added dropwise 75 ml of 1.4M sec-butyllithium in hexane. After 1 hour 9.7 ml of freshly distilled dimethylformamide in 20 ml of tetrahydrofuran was added and stirring was continued for 2 hours at room temperature. The mixture was poured into water (200 ml) and extracted with diethylether (2×100 ml), dried and evaporated to yield the crude product. Vacuum distillation, bp 140°-150° C./0.4mm gave the title compound as a pale yellow oil.
