Reaction Steps
2-(5-Methyl-2-phenyl-4-oxazolyl)ethanol (0.203 g, 1.0 mmol; European patentapplication 177353) and CBr4 (0.662 g, 2.0 mmol) were dissolved in 10 mL of ether and cooled to 0° C. Triphenylphosphine (0.524 g, 2.0 mmol) was added and the mixture stirred for 3 hours at room temperature. The mixture was filtered, the filtrate was stripped of solvent and the residue filtered through a plug of silica gel using CHCl3 as eluant to yield 0.16 g of present title product as a white solid; mp 59°-61° C.; tlc Rf 0.22 (CHCl3).
