PROCEDURE
实验过程
1.7 g of glutaric anhydride was added to a solution of 4.0 grams of alanyl-alanyl proline ethylamide in 25 ml of dimethylformamide and the reaction solution heated for 1 hour at 60 degrees C. Then, the solution was evaporated and the resultant non-crystalline evaporation residue dissolved in 30 ml of ethyl acetate. After 48 hours of standing at 3 degrees C., 3.6 g of separated product was filtered off with a melting point of 154 to 156 degrees C. ([α]D20 -137.3 degrees (c 0.3; 50% methyl alcohol).
