Is there a way to synthesize 4CMC? Start with 4-Chloropropenolone

[Taiwan]

This is the material I used

4-Chloropropenolone 1kg
Bromine 300ml
Dichloromethane 3000 ml
Monomethylamine 40% 1500 ml
Toluene 3000 ml
Hydrochloric acid 37%

After bromination, there are 1400 grams of 2b4c. After amination, add hydrochloric acid 37% PH6. The product is very dirty and black. The yield of powder is only 40% of the product.
