The reaction lasts for several days and is monitored by thin-layer chromatography until the raw material is almost non-existent, and Boc-D - β - alanine.
times, the resulting Boc - D - β - alanine and iodine substitution reagent, such as cuprous iodide and iodine mixed system, in a specific solvent, such as N, N - dimethylformamide (DMF), under heating conditions. The heating temperature should be controlled in a moderate range, about 60 - 80 ℃, after several times of reaction, the β position is successfully introduced into the iodine atom, and then the monitoring means is used to confirm the progress and degree of the reaction to obtain Boc - D - β - iodine - alanine.
Finally, Boc-D - β - iodine-alanine are mixed with methanol and catalytic concentrated sulfuric acid, and reacted under heating reflux to esterify the carboxyl group with methanol to obtain Boc-D - β - iodine-ala-ome. After the reaction, the pure product is obtained by various separation and purification methods such as neutralization, extraction, and column chromatography. The whole process requires fine operation and attention to the control of reaction conditions to obtain the product with ideal yield and purity.
