Procedure

Under N2, oxalyl chloride (262 ml) was dissolved in 1 liter anhydrous ether and heated to reflux, at which temperature benzyl alcohol (207 ml) was added over 70 minutes. After refluxing a further 16 hours, ether was stripped and the residue distilled at reduced pressure to yield 372 g (94%) of title product, b.p./0.7 mm 85° C.
