実験手順

100 mg of 5,5,6,6-tetramethyl-2-(4-nitrophenoxy)-5,6-dihydro-1,4,3-oxathiazine 4,4-dioxide and 97 mg of 3-((S)-1-amino-3-hydroxypropyl)benzonitrile hydrochloride were dissolved in 5 ml of dichloromethane and 0.25 ml of N,N-diisopropylethylamine, and the mixture was stirred at room temperature for 16 hours. Subsequently, the reaction solution was diluted with 20 ml of dichloromethane, and washed with 10 ml of 10% aqueous ammonia solution and with 10 ml of 1 N aqueous hydrochloric acid. The two aqueous phases were extracted once again with 20 ml of ethyl acetate, and the combined organic phases were dried over Na2SO4 and concentrated by rotary evaporation. The residue was purified in a purification laboratory by means of preparative HPLC. After lyophilization of the product-containing fractions, the product (66 mg) was thus obtained with a molecular weight of 365.5 g/mol (C17H23N3O4S); MS (ESI): m/e=366 (M+H+).
