Synthesis of Compound 32.1 [0281] To a solution of potassium l,3-dioxoisoindolin-2-ide (18.5 g, 0.1 mol, 1.0 eq) in acetone (200 mL) was added 1,6-dibromohexane (43.5 g, 0.18 mol, 1.8 eq). The mixture was stirred at 65 C for 12 h. After cooling down, the mixture was filtered to remove the precipitated salt. The filtrate was concentrated and the residue purified by a short silica gel column (PE : EA = 10 : 1) to remove the excess 1,6-dibromohexane. 16.1 g of 32.1was obtained as a yellow oil (yield: 52%). 1H NMR (400MHz, DMSO- 6)D delta: 7.88-7.82 (m, 4H), 3.58-3.49 (m, 4H), 1.81-1.74 (m, 2H), 1.63-1.55 (m, 2H), 1.44-1.27 (m, 4H); ESI-MS (M+H) +: 312.1.

According to the analysis of related databases, 1074-82-4, the application of this compound in the production field has become more and more popular.
