Reaction Steps

320 mg of (S)-6-(4-tert-butoxycarbonyl-2-methyl-1,4-diazepan-1-ylsulfonyl)isoquinoline 2-oxide was dissolved in dichloromethane, and 0.1 mL of ethyl chlorocarbonate, 0.42 mL of 2-(N-tert-butoxycarbonylamino)ethanethiol, and 0.21 mL of triethylamine were added at 0° C. The reaction solution was stirred at room temperature for 16 hours and then concentrated under reduced pressure, and the obtained crude product was purified by silica gel column chromatography (hexane:acetone=4:1) to obtain 223 mg of the compound of interest as a colorless oil (51%).
