HCID 214274141-[2-(Tetrahydro-2-oxo-1,3-oxazin-3-yl)ethyl]-3-phenylurea

Procedure

When 3-chloropropanol is reacted with 1-(2-aminoethyl)-3-phenylurea and the resulting 1-[2-(3-hydroxypropylamino)ethyl]-3-phenylurea is reacted with diethyl carbonate according to the general processes of steps 1 and 2 of Example 2, there is obtained 1-[2-(tetrahydro-2-oxo-1,3-oxazin-3-yl)-ethyl]-3-phenylurea.
