Versuchsvorschrift

A solution of the compound (4.1 g, 15 mmol) obtained in Example 25-2) and 7-({[tert-butyl(dimethyl)silyl]oxy}methyl)-7-methyl-5-(methylthio)-2,3,6,7-tetrahydro-1,4-thiazepine (4.79 g, 15 mmol) in n-butanol (30 mL) was stirred at 140° C. for 3.5 h. The reaction mixture was cooled to room temperature and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (Isco Combiflash, 40 g, ethyl acetate:dichloromethane=0:100 to 100:0, gradient) to obtain the title compound (3.47 g, 44%) as a brown solid.
