Reaction Steps

By using [4-cyano-5-methyl-4-(2-bromo-5-thienyl)hexyloxy]-tert-butyldimethylsilane (700 mg) which was obtained in Example 114-5) described in JP-A 11-206862, 4-cyano-5-methyl-4-(2-bromo-5-thienyl)hexanol (371 mg, 80%) was synthesized as a yellow oil in accordance with Example 114-8) described in JP-A 11-206862. From 105 mg of the resulting compound and 96 mg of 2-(3-cyanophenoxy)ethylpiperazine, the title compound was synthesized as a colorless oil in accordance with the production method described in Example 84 (138 mg, 62%).
