Procedure

A solution of 7-({[tert-butyl(dimethyl)silyl]oxy}methyl)-7-methyl-5-(methylthio)-2,3,6,7-tetrahydro-1,4-thiazepine (39.7 g, 124 mmol) and the compound (19.5 g, 70.1 mmol) obtained in Example 60-3) in 1-butanol (750 mL) was stirred at 140° C. for 13 h. The reaction mixture was cooled to room temperature, the solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate:methanol=9:1) to obtain the title compound (33.1 g, 89%) as a white solid.
