PROCEDURE

实验过程

To a rt solution of (3S,4S)-3-amino-4-methyl-1-((2-methylnaphthalen-1-yl)methyl)-5-(2-(methylsulfonyl)acetyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepine-7-carbonitrile hydrochloride (100 mg, 190 μmol) in DMF (632 μl) was added (S)-2-(tert-butoxycarbonyl(methyl)amino)butanoic acid (45.3 mg, 209 μmol), N,N-diisopropylethylamine (131 μl, 759 μmol), and HBTU (79.2 mg, 209 μmol). The reaction was stirred at rt for 30 min, then purified by reverse phase preparative HPLC to provide tert-butyl(S)-1-((3S,4S)-7-cyano-4-methyl-1-((2-methylnaphthalen-1-yl)methyl)-5-(2-(methylsulfonyl)acetyl)-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxobutan-2-yl(methyl)carbamate (118 mg, 90%) as a white solid. MS m/z 712 (MNa)+.
