반응 단계
Gaseous HBr was passed into a solution of 3 g. of 3-pyridylmethyl-3-(4-nitrophenyl)urea in the monomethyl ether of ethyleneglycol. Ether was added to give a precipitate and after isolation, washing with ether and drying, 2.95 g. of white solid was obtained. This was a 76% yield of 1-(3-pyridylmethyl)-3-(4-nitrophenyl)urea hydrobromide.
