Participants

Reaction Steps

To a solution of 40 mg of 4-[2-((S)-3-hydroxy-1-phenylpropylamino)-6,6-dimethyl-4,4-dioxo-5,6-dihydro-4H-4lambda6-1,4,3-oxathiazin-5-yl]phenol in 1 ml of N,N-dimethylformamide were added, at room temperature, 11 mg of potassium tert-butoxide and 28 mg of methyl iodide, and the reaction mixture was stirred at constant temperature for 3 hours. The reaction solution was purified in a purification laboratory by means of preparative HPLC. The product-containing fractions were combined and lyophilized. This gave the product (10 mg) with a molecular weight of 418.5 g/mol (C21H26N2O5S); MS (ESI): m/e=419 (M+H+).
