実験手順

A mixture of (4-(pyridin-2-yloxymethyl)-phenyl)methanol (540 mg, 2.51 mmol) described in Manufacturing Example 2-1-1, triphenylphosphine (856 mg, 3.27 mmol) and carbon tetrachloride (10.8 g, 10.2 mmol) was stirred under reflux for 2 hours and 10 minutes. The reaction solution was cooled to room temperature, and concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (heptane:acetic acid=8:1) to obtain the title compound (300 mg, 51.1%).
