To a solution of Fmoc-L-Cys(Trt)-OMe (2.58 g, 4.30 mmol) in acetonitrile (20.0 mL) was added diethylamine (20.0 mL). After 30 minutes, the mixture was concentrated in vacuo. The residue was dissolved in acetonitrile (3×10 mL) and concentrated in vacuo to afford L-Cys(Trt)-OMe as crude product which was used without purification.
