| Product | 3-(3-Isopropyl-4-methoxybenzylidene)-1,3-dihydroindol-2-one | HCID 53799055 | — |
Reaction Steps
2-Isopropylphenol was methylated and then formylated to give 3-isopropyl-4-methoxybenzaldehyde. 3-Isopropyl-4-methoxybenzaldehyde was condensed with 2-oxindole to give 0.3 g of 3-(3-isopropyl-4-methoxybenzylidene)-1,3-dihydroindol-2-one as a yellow-orange solid.
