According to a similar procedure to that described in Example 1-(10), 2-[(tert-butyldimethylsilyl)oxymethyl]-6-methylbenzylalcohol (4.92 g, 18.5 mmol) obtained from Example 22-(2), tetrazole (3.23 g, 46.2 mmol), bis(allyloxy)(diisopropylamino)phosphine (described in Tetrahedron Lett., 30, 4219 (1989); 5.43 g, 22.2 mmol), and tert-butyl hydroperoxide (80% di-tert-butyl peroxide solution; Merck; 1.8 g, 16 mmol) were reacted, and the reaction mixture was worked up to afford, after extraction, an oily residue. The residue was subjected to chromatography on a silica gel (200 g) column (eluent; ethyl acetate:hexane=1:4˜2:3) to afford the title compound (6.03 g, 74% yield) as a colorless oil.
