Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 3891-07-4, name is 2-(2-Hydroxyethyl)isoindoline-1,3-dione, A new synthetic method of this compound is introduced below., Recommanded Product: 2-(2-Hydroxyethyl)isoindoline-1,3-dione
Step 2; 126 1272-(2-(benzyloxy)ethyl)isoindoHne-l,3-dione (127): A solution of 126 (5 g, 26 mmol) in DMF (50 mL) was treated with sodium hydride (1.1 g, 32 mmol, 70 % dispersed in mineral oil) for 30 minutes at room temperature, followed by addition of BnBr (6.7 g, 39 mmol). After additional 1 hour, the reaction was quenched by water (200 mL) and extracted with ethyl acetate (4×50 mL). The combined organic layer was washed with brine (3×50 mL), dried over anhydrous sodium sulfate and concentrated under vacuum to give a residue, which was purified by a silica gel column, eluted with 10 % – 20 % ethyl acetate in petroleum ether to afford 127 as a white solid (4.8 g, 65 %).(ES, m/z) [M+H]+ 282.0; NMR (300 MHz, CDC13) 6 7.85 – 7.88 (m, 2H), 7.71 – 7.74 (m, 2H), 7.25 – 7.31 (m, 5H), 4.55 (s, 2H), 3.95 (t, J= 6.0 Hz, 2H), 3.74 (t, J= 6.0 Hz, 2H).
The synthetic route of 3891-07-4 has been constantly updated, and we look forward to future research findings.
