Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 91476-80-1, name is 5,6,7,8-Tetrahydroimidazo[1,2-a]pyrazine, This compound has unique chemical properties. The synthetic route is as follows., name: 5,6,7,8-Tetrahydroimidazo[1,2-a]pyrazine
Step A: To a solution of NaH (60% dispersion in mineral oil, 0.130 g, 3.25 mmol) in THF (10 mL) was added 5,6,7,8-tetrahydroimidazo[1,2-a]pyrazine (0.33 g, 2.71 mmol) and the reaction mixture stirred for 10 min. Methyl 2-chlorobenzoxazole-4-carboxylate (478 mg, 2.26 mmol), in THF (10 mL) was added and the reaction mixture was allowed to stir at room temperature 17 h. The reaction mixture was quenched with CH3OH (3 mL), and adsorbed onto silica gel (2 g). The crude product was purified by column chromatography (silica gel, 0.5 to 10% CH3OH in CH2Cl2) to afford methyl 2-(5,6-dihydroimidazo[1,2-a]pyrazin-7(8H)-yl)benzoxazole-4-carboxylate (251 mg, 37%) as an orange oil. 1H NMR and MS consistent.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 91476-80-1.
