Abstract
The structure of title product was determined by single crystal X-ray diffraction.The title compound(C23H21Br2NO2)has been synthesized by the reaction of 1-(4-Bromo-phenyl)-2,2-dihydroxy-ethanone,3-((4-Bromophenyl)amino)-5,5-dimethylcyclohex-2-enone,methanol and pTsOH as catalyst in methanol under microwave radiation.The crystal is triclinic,space group P-1,with Mr=503.23,a=0.884 19(9)nm,b=0.969 36(11)nm,c=1.348 97(13)nm,V=1.070 96(19)nm3,Z=2,μ=3.803mm-1,F(000)=504.The structure was solved by direct methods and refined by full-mat rix least squares method to the final R=0.058 4,wR=0.107 8.X-ray analysis reveals that the formation of new pyrrole ring in the crystal structure is a planar structure.
