実験手順
To a stirred solution of CBZ-L-Pro-OH (0.62 g, 2.49 mmol) and a drop of DMF in methylene chloride (10 ml) under argon was added oxalyl chloride (0.26 ml; 2.99 mmol) which resulted in a vigorous evolution of gas. After the evolution of gas ceased, the reaction was stirred for an additional 30 minutes. The reaction was then concentrated to give, as a light yellow oil, N-carbobenzoxy-L-prolyl chloride (CBZ-L-Pro-Cl).
