- Molecular formula:C14H11NO3
- Molecular Weight:241.24
Yield:14064-83-6 98%
Reaction Conditions:
with piperidine at 140; for 2 h;
Steps:
8 Example 8: Synthesis of (E)-2-((2-(2,6-dioxopiperidin-3-yl)-1.3-dioxoisoindolin-4-yl)oxy)-N-(2-(2-(2-(4-(4-(methylamino)styryl)phenoxy)ethoxy)ethoxy)ethyl)acetamide (12)
A mixture of 2-(4-nitrophenyl)acetic acid (18g, 100 mmol) and 4-hydroxybenzaldehyde (24 g, 200 mmol) in piperidine (6 mL) was stirred at 140°C for 2 hours. The solid was washed with EtOAc to give (E)-4-(4-nitrostyryl)phenol as a red solid (23.6 g, 98%).
