I manufactured etomidate using the method described in patent number CN114456118A, but I used his example method and none of them were successful. In the first step, I perfectly obtained the product, but in the second step, I was unable to obtain what I wanted. In addition, I have also tried the example step in patent number US3354173A, but it still fails. There are too many magazines, and the target product yield is less than 15%.
I have never understood why, so I am here to see if I can find an answer. Thank you.
