Procedure

A stirred solution of 4.0 grams (0.02 mole) of (4-pyrimidin-2-yloxyphenyl)methanol (known compound) and seven drops of pyridine in 35 mL of methylene chloride was cooled in an ice-water bath and a solution of 2.0 mL (0.027 mole) of thionyl chloride was added dropwise. Upon completion of addition the reaction mixture was stirred at about 10° C. to 20° C. during a three-hour period. After this time, the reaction mixture was poured into a cold aqueous solution of sodium bicarbonate. The mixture was then stirred for 30 minutes and the organic layer was separated. The aqueous layer was extracted with one 50 mL portion of methylene chloride. The extract was combined with the organic layer, and the combination was passed through silicone-coated filter paper to remove traces of water. The filtrate was concentrated under reduced pressure, yielding grams of the subject compound. The NMR spectrum was consistent with the proposed structure.
