Reaction Steps
A mixture of 0.00282 mol of 2-isopropyl-3-[4-(3-bromopropyloxy)benzenesulphonyl]furan and 0.013 mol of tert-butylamine in 7 ml of dimethylsulphoxide was stirred at room-temperature for 24 hours. After that, the mixture was poured into water, distilled in the presence of ethyl acetate, dried on sodium sulphate, filtered and concentrated. The residue so obtained was purified on a silica column using a methanol/ethyl acetate 2/8 mixture as eluent. The oily base so provided was then treated with an ethereal solution of oxalic acid and the precipitate was recrystallized from ethanol.
