실험 절차

A mixture consisting consisting of 2-amino-4-(5,6,7,8-tetrahydro-2-naphthyl)thiazole (500 mg), benzoylisothiocyanate (363 mg) and acetone (10 ml) was stirred at 55° to 60° C. for 3 hours and then concentrated under reduced pressure. The residue was treated with ether, and the resultant crystals were recrystallized from chloroform-ethanol to produce 1-benzoyl-3-[4-(5,6,7,8-tetrahydro-2-naphthyl)-2-thiazolyl] thiourea (yield of 583 mg, 68.2%) in the form of colorless prisms. m.p., 181°-182° C.
