The crude product of the title compound was synthesized by conducting the reaction similar to that mentioned in Example 24 (24f) using (4-bromo-2-methylphenyl)methanol (3.7 g, 19 mmol) that was obtained in Example 27 (27a) and pyridinium dichromate (11g, 28 mmol). Subsequently, the crude product of the title compound thus obtained was purified by chromatography on a silica gel column using a mixed solvent of ethyl acetate and hexane (1:19 to 1:4) as the eluent to afford the title compound (2.4 g) in a yield of 64% as a colourless oily product.
