HCID 3628438Urea, (1,2,3,4-tetrahydro-4-oxo-1-naphthalenyl)-Yield 72.7%

Procedure

A mixture of 1-benzoyl-3-(1,2,3,4-tetrahydro-4-oxo- 1-naphthyl)urea (3.8 g) and aqueous sodium hydroxide (2N; 38 ml) is stirred and heated at reflux for 70 minutes. The mixture is then cooled in ice and the product is collected and washed with water to afford 1.83 g of the title compound, m.p. 212° to 215° C.
