Reaction Steps
A solution of 55.6 mg product from Step E above, 28.8 mg EDC, 20.3 mg HOBt in 1 mL DMF was stirred at room temperature for 45 minutes. 5-Aminotetrazole monohydrate (15.5 mg) was added and the mixture stirred for additional 22 hours. DIEA (26 μL) and more EDC (13.8 mg) were added and the reaction continued for another day. The title compound was isolated on preparative HPLC using 75˜90% MeCN gradient over 10 minutes at 8.0 mL per minute with 0.1% TFA as a white solid following lyophilization. LC-MS: 2.26 min. (M+H=512.1).
