In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Ethyl 2-amino-2-oxoacetate, other downstream synthetic routes, hurry up and to see.

Reference of 617-36-7, The chemical industry reduces the impact on the environment during synthesis 617-36-7, name is Ethyl 2-amino-2-oxoacetate, I believe this compound will play a more active role in future production and life.

Step 1: Preparation of N-(2,2,6,6-tetramethyl-4-piperidinyl)oxamide Into a 3-neck, 250 ml, round bottom flask was added 30.5 g (0.25 mole) of ethyl oxamate (Aldrich Chemical Company) and 100 ml of methanol. The flask was equipped with a magnetic stirrer, thermometer, reflux condenser and addition funnel containing 39.0g (0.25 mole) 4-amino-2,2,6,6-tetramethylpiperidine. The stirrer was activated and the amine was added dropwise to the ethyl oxamate solution over 12 minutes as the temperature slowly rose to 35C. The reaction was stirred an additional 2.5 hours and filtered. After air drying overnight, the filter cake weighed 40.4g and had a melting point of 203-208C. The filtrate was transferred back to the 250 ml 3-neck flask and another 30.5g of ethyl oxamate was added. An additional 39g of 4-amino-2,2,6,6-tetramethylpiperidine were added over 7 minutes as the temperature slowly rose to 28C. The reaction was stirred 3 hours and filtered. After air drying overnight, the filter cake weighed 50.0g and had a melting point of 198-200C. The infrared spectrum (nujol mull) of the product contained a sharp NH band at 3370 cmmin1, a strong broad carbonyl band at 1670 cmmin1 and a weaker carbonyl band at 1520 cmmin1.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Ethyl 2-amino-2-oxoacetate, other downstream synthetic routes, hurry up and to see.
