A novel and convenient one-step method for the synthesis of 1,3,4,-Triaryl-substituted- 3,4,5,6-tetrahydropyrimidin-2(1H)-ones (3) was developed by cyclization of aromatic isocyanates (1) with 3-arylamino-1-phenylpropan-1-ones (2) under refluxing of toluene. Effects of reaction conditions on the converting ratio and yield were investigated. The method offered several advantages including simple experimental procedure, easily available starting materials and excellent yields (79%~96%).

Key words: aromatic isocyanate, cyclization, 3-arylamino-1-phenylpropan-1-one, 3,4,5,6-tetrahydro- pyrimidin-2(1H)-one
