YieldReaction ConditionsOperation in experiment
80% With toluene-4-sulfonic acid; In toluene; at 110℃; for 24h; As shown in Scheme 5 below, to 100 mL of toluene in which 5.28 g (27.7 mmol) of p-toluenesulfonic acid (p-TSA ), 20.0 g (138.7 mmol) of <strong>[51792-34-8]3,4-dimethoxythiophene</strong> (compound (1)) and 2-methyl-2-Propyl-1,3-propanediol, compound (8)) were mixed and stirred at 110 DEG C for 24 hours. After completion of the reaction, a mixed solvent of water and ethyl acetate (EtOAc) was added to the reaction product, extracted, washed with brine, water removed using anhydrous Na2SO4, filtered and concentrated. The water was separated by column chromatography on SiO2 (eluent: hexane: ethyl acetate = 10: 1) to give 3-methyl-3-propyl-3,4-dihydro-2H-thieno [3,4-b] [1,4] dioxepin -B] [1,4] dioxepine, compound (9)) (yield: 65-80percent). Of the obtained compound 1H-NMR the data is as follows : 1H-NMR (CDCl3, Varian 400 MHz) : delta 0.93-0.96 (6H, m), 1.29-1.45 (4H, m), 3.69-3.88 (4H,m), 6.45 (2H, s).
