A solution of 2-hydroxybenzyl alcohol (5 g, 40 mmol) in methanol (25 mL) was heated in a sealed vessel at 150° C. for 4 hours. The reaction mixture was then concentrated in vacuo and the residue was purified by fractional distillation (90° C./10 mm Hg) to afford the title compound as a colourless liquid in 58% yield, 3.22 g. LRMS APCI m/z 137 [M−H]−
