Abstract:Nabumetone was prepared from 4-(6-methoxy-2-naphthyl)-1,3- butandione by catalytic hydrogenation. Main interacting factors such as catalyst,solvent,dehydrating agent,temperature,pressure and reaction time were studied. The optimum conditions were as follows:40℃,0.4 MPa,Pd/C(10%)as catalyst,THF as solvent,2% p-toluene sulfonic acid as dehydrating agent and reaction time 4 hours. Under above conditions,the yield of nabumetone was up to 88.3% with the purity of 99.1% after recrystallization. |
Key words:nabumetone;catalytic hydrogenation;orthogonal design |
