yield. By hydrolysis of 9, 6-(1-naphthyl)uracil was obtained in 98% of isolated yield. When the three steps (SRN1 reaction−cross coupling reaction−hydrolysis) were performed in a one-pot reaction, 6-substituted uracils (1-naphthyl, 4-chlorophenyl, 3-chlorophenyl, 2,3,4,5,6-pentafluorophenyl) were obtained (43−57%) of isolated pure products. When the electrophile was a benzoyl chloride, 6-benzoyl uracil
