実験手順
325 mg of (2S,3S)-4-benzyloxy-2,3-epoxy-1-butanol tert-butyldimethylsilyl ether obtained in Example 53. was subjected to Grignard reaction in the same manner as in Example 53 by using 3-tolylmethyl magnesium bromide (0.8M diethyl ether solution). The product was purificated by silica gel column chromatography to obtain 210 mg of (2R,3R)-4-benzyloxy-1-tert-butyldimethylsilyloxy-3-(3-tolylmethyl-2-butanol as colorless oily substance.
