The synthetic route is as follows., HPLC of Formula: C6H9N3
5,6,7,8-Tetrahydroimidazo[1 ,2-a]pyrazine(l17) (4.53 g, 36.8 mmol) and triethylamine (6.16 mL, 44.2 mmol) were dissolved in dichloromethane (DCM) (200 mL) and treated with di-tert-butyl dicarbonate (10.25 mL, 44.2 mmol). The solution was stirred at RT for 48 h and concentrated in vacuo to afford a crude oil. The crude product was purified by flash chromatography (Isolera, 340 g, 0-100% 2M ammonia in methanokdichloromethane (1 :9)/dichloromethane) to afford 3 fractions. Fraction 2 was identified by LC/MS as containing desired product. The residue was dissolved in ethyl acetate (300 ml), washed with saturated sodium bicarbonate solution (50 ml_), water (2 x 50 ml_), brine (50 ml_), dried over anhydrous sodium sulfate and concentrated to afford product in 6.77g. LC/MS = 224 (M+H)+, retention time = 0.71 minutes (2 minute method (high pH)).
According to the analysis of related databases, 91476-80-1, the application of this compound in the production field has become more and more popular.
