Bicyclo[2.2.2]octan-1-amine hydrochloride → 4-Aminobicyclo(2.2.2)octane

300 mg of 5,5,6,6-tetramethyl-2-(4-nitrophenoxy)-5,6-dihydro-1,4,3-oxathiazine 4,4-dioxide and 163 mg of 1-aminobicyclo[2.2.2]octane hydrochloride were dissolved in a mixture of 5 ml of dichloromethane and 0.38 ml of N,N-diisopropylethylamine, and the mixture was stirred at room temperature for 72 hours. Subsequently, the reaction solution was concentrated by rotary evaporation and the residue was purified in a purification laboratory by means of preparative HPLC. After lyophilization of the product-containing fractions, the product (166 mg) was thus obtained with a molecular weight of 314.5 g/mol (C15H26N2O3S); MS (ESI): m/e=315 (M+H+).
