Embodiment example 1
[0022] Step 1: Add glycinamide hydrochloride (0.095mol) into a three-necked flask equipped with mechanical stirring and placed in an ice bath, blow nitrogen gas, add 10ml of ice water, and stir until completely dissolved. 40ml ice ether and 55ml ice 2mol L -1 K 2 CO 3 The solutions were successively added into the flask, 0.10 mol of acryloyl chloride was dissolved in 40 ml of ether, and added dropwise into a three-necked flask under stirring at 500 rpm, and then reacted at room temperature for 2 hours. Use 6M HCl solution to adjust the pH of the solution to 2. After removing the organic phase, the aqueous solution is washed three times with ether, the color of the solution is removed with charcoal, and filtered. The residual ether is removed by rotary evaporation at 20°C, and then the pH of the solution is adjusted with 2M NaOH solution. Adjust to neutrality, freeze-dry to obtain a crude product, wash three times with ethanol / methanol (4 / 1, v / v) solution, and obtain NAGA aft...
