Participants

Reaction Steps

Following a procedure similar to that described above in part B of this example by using 4-(1-n-butyl-5-methoxy-3-indolyl)-2,3-dichloro-4-oxo-2-butenoic acid instead of 4-(1-ethyl-2-methyl-3-indolyl)-2,3-dichloro-4-oxo-2-butenoic acid and 1-(3-chlorobenzyl)-2-ethylindole is substituted for 2-methylindole, there is obtained 5-(1-n-butyl-5-methoxy-3-indolyl)-5-[1-(3-chlorobenzyl)-2-ethyl-3-indolyl]-3,4-dichloro-2(5H)-furanone (Formula V: R=CH3 (CH2)2CH2 ; R1 =Y1 =H; R2 =3--ClC6H4CH2 ; R3 =CH3CH2 ; Y=5--CH3O).
