[0002] L-prolineamide is a raw material for health care products, a pharmaceutical intermediate, a vildagliptin intermediate product, and an important optically active pyrrole derivative. It can directly catalyze asymmetric Robinson cyclization reactions, Al do l reactions, etc. It is an important intermediate in peptide synthesis and can also be used as a chiral intermediate to synthesize certain chiral drugs. In the preparation process of L-prolineamide, various reagents need to be subjected to a constant temperature reaction in a heat preservation device. However, the current constant temperature device used for storage is not convenient to place according to the length and specifications of the preparation test tube during use, resulting in poor practicality of the storage device, and it is also easily affected by the external temperature to cause temperature changes.
