Bromoacetonitrile → HCID 89668616, compound

Participants

Reaction Steps

N,N-Diisopropylethylamine (81 μL, 0.463 mmol) and subsequently bromoacetonitrile (147 μL, 2.103 mmol) were added to a solution of Boc-Lys(Z)-OH (Compound tk44) (160 mg, 0.421 mmol) in acetonitrile (0.6 mL) at room temperature under a nitrogen atmosphere. The reaction mixture was stirred at the same temperature for 13 hours and then concentrated under reduced pressure, and the resulting crude product was purified by normal-phase silica gel column chromatography (hexane/ethyl acetate) to afford (S)-cyanomethyl 6-(((benzyloxy)carbonyl)amino)-2-((tert-butoxycarbonyl)amino)hexanoate (Compound tk45) (180 mg, quant.).
