Example Embodiment
[0021] Implementation case 1
[0022] Step 1: Add glycinamide hydrochloride (0.095 mol) into a three-necked flask equipped with mechanical stirring and placed in an ice bath, vent nitrogen, add 10 ml of ice water, and stir until completely dissolved. 40ml ice ether and 55ml ice 2mol·L -1 K 2 CO 3 The solution was successively added to the flask, 0.10 mol of acryloyl chloride was dissolved in 40 ml of ether, and added dropwise to a three-necked flask under stirring at 500 rpm, and then reacted at room temperature for 2 hours. Adjust the pH of the solution to 2 with 6M HCl solution. After removing the organic phase, wash the aqueous solution with ether three times, remove the color of the solution with charcoal, filter, and remove the remaining ether by rotary evaporation at 20°C. Then use 2M NaOH solution to adjust the pH of the solution. Adjust to neutral, freeze-dry to obtain crude product, wash with ethanol / methanol (4 / 1, v / v) solution three times, and obtain NAGA after solvent...

[0029] Implementation case 3
[0030] Step 1: Add glycinamide hydrochloride (0.095 mol) into a three-necked flask equipped with mechanical stirring and placed in an ice bath, vent nitrogen, add 10 ml of ice water, and stir until completely dissolved. 40ml ice ether and 55ml ice 2mol·L -1 K 2 CO 3 The solution was successively added to the flask, 0.10 mol of acryloyl chloride was dissolved in 40 ml of ether, and added dropwise to a three-necked flask under stirring at 500 rpm, and then reacted at room temperature for 2 hours. Adjust the pH of the solution to 2 with 6M HCl solution. After removing the organic phase, wash the aqueous solution with ether three times, remove the color of the solution with charcoal, filter, and remove the remaining ether by rotary evaporation at 20°C. Then use 2M NaOH solution to adjust the pH of the solution. Adjust to neutral, freeze-dry to obtain crude product, wash with ethanol / methanol (5 / 1, v / v) solution three times, and obtain NAGA after solvent...
