Participants

Reaction Steps

A 7 M ammonia-methanol solution (2 ml) was added to ethyl 5-(benzo[b]thiophen-4-ylamino)-3-((1R,2S)-2-(tert-butoxycarbonylamino)cyclohexylamino)-1,2,4-triazine-6-carboxylate obtained in the above-described Step 2 (71.8 mg), and then the reaction solution was allowed to react in a microwave reactor at 130° C. for 1 hour. The solvent was evaporated under vacuum, then trifluoroacetic acid (0.5 ml) was added to the resultant residue, and the reaction solution was stirred at room temperature for 5 minutes. The solvent was evaporated under vacuum, and then the resultant residue was purified by column chromatography on basic silica gel (developing solvent:hexane/ethyl acetate) to obtain the titled compound as a white solid.
