L-Alaninamide hydrochloride Use and Manufacturing
500g of methanol, L-Alanine of 100g were placed in a 1000ml of three necked flask, then 90ml of Thionyl chloride was added dropswise (T≤35°C). After the addition was completed, the three-necked flask was transferred to a water bath and the temperature was raised to reflux (T≤35°C), and fully removed SO2. In the ice bath(T≤20°C), ammonolysis was performed on 0.56 kg of ammonia, and seal in a water bath at room temperature overnight (20 hours). The water bath was warmed to Τ=55°C to remove ammonia cocentration, the final concentration volume was 300 ml and removal of ammonia concentration was complete. The excess ammonium chloride was filtered, rinsed with 100 ml of methanol, rinsed liquid combined with the mother liquor and transferred to a 1000 ml beaker. 34.5 ml of hydrochloric acid (10percent concentration) was slowly added dropwise to adjust the pH to 1.55 and the acid adjustment was completed. After being sealed in a refrigerator and refrigerating for 12 hours, after taking out, 400 ml of acetone was added, and crystals were precipitated. After suction filtration, rinsing, and drying at 45° C for 12 hours, 85 g of white crystals were obtained (yield was 85percent).See the test results [a] =+11.4°
L-Alanine Amide is used for preparation of novel amide derivatives of steroidal[3,2-c]pyrazole compounds with glucocorticoid activity.
