반응 단계
Following a procedure similar to that described above in Example 25, part B, 5.0 g (0.017 mole) of 4-(2-methyl-3-indolyl)-2,3-dichloro-4-oxo-2-butenoic acid and 2.7 g (0.017 mole) of 1-ethyl-2-methylindole were interacted to obtain 5-(2-methyl-3-indolyl)-5-(1-ethyl-2-methyl-3-indolyl)3,4-dichloro-2(5H)-furanone (Formula V: R=Y=Y1 =H; R1 =R3 =CH3 ; R2 =CH3CH2) as a red-blue solid which melted in the range of 282°-285° C.
