実験手順
Ethyl ((1S)-5-{3-[4-(aminocarbonothioyl)-2-methoxyphenoxy]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (1.00 g, 2.3 mmol) (Example 146) and bromoacetaldehyde diethyl acetal (1.78 g, 9.2 mmol) were dissolved in EtOH (30 mL) and water (2 drops) was added. The mixture was heated at 70° C. for 18 h, and then the reaction mixture was cooled to rt, and concentrated under reduced pressure. Purification by silica gel flash chromatography (EtOAc:hexane (v/v)=1:1) gave 610 mg (58%) of the title compound as a clear oil. LC-MS: RT=3.81 min; (M+H)+ 468.1.
