To a solution of (5S)-2,2-dimethyl-5-((1S)-3-methyl-1-{[4-(3-phenyl-1,2,4-thiadiazol-5-yl)-1-piperazinyl]carbonyl}butyl)-1,3-dioxolan-4-one (9.0 mg; 0.019 mmol; 1.0 eq.) in iPrOH (0.20 mL) was added an aqueous solution of hydroxylamine (50%; 0.0029 mL; 0.098 mmol; 5.0 eq.) and the resulting reaction mixture was stirred at RT for 2 h. Evaporation of the solvents gave the title product (2) as a colorless oil (9 mg; 100%). M−(ESI): 432.1; M+(ESI): 434.3. HPLC (Condition A): Rt: 3.1 min (HPLC purity: 79.3%).
