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. 77112-52-8, name is Ethyl imidazo[1,2-a]pyrazine-2-carboxylate, This compound has unique chemical properties. The synthetic route is as follows., Quality Control of Ethyl imidazo[1,2-a]pyrazine-2-carboxylate
Step 2: 5, 6,7, 8-Tetrahydroimidazo [1,2-a] pyrazine-2-carboxylic acid ethyl ester, Hydrochloride :; 0.46 M HCI-EtOH (169 mL) and 10% Pd-C (50% wet) (1.37 g) were added to the EtOH (546 mL) solution of imidazo [1,2-a] pyrazine-2-carboxylic acid ethyl ester (13.7 g). The mixture was hydrogenated under H2 at 40 psi at room temperature for 15 h. The reaction mixture was filtered and Pd-C was washed with EtOH. The filtrate was concentrated under reduced pressure. The residue was applied to silica gel column chromatography, then the column was eluted with CHCI3-MeOH (9/1- 2/1). The titled compound was obtained as brown crystals Yield : 10.4 g, 63%. ‘H NMR (CDCI3) 8 d 1.38 (t, 3H, J = 7.1 Hz), 3.90 (t, 2H, J = 5.7 Hz), 4.40 (q, 2H, J= 7.1 Hz), 4.59 (t, 2H, J= 5.7 Hz), 4.80 (s, 2H), 8.20 (s, 1H).
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 77112-52-8.
