Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 31037-02-2, name is Ethyl 5-amino-1-methyl-1H-pyrazole-4-carboxylate, A new synthetic method of this compound is introduced below., COA of Formula: C7H11N3O2<\/a><\/p>\n

INTERMEDIATE 1 Ethyl 5 – [(3 -ethoxy-3 -oxopropanoyQamino] – 1 -methylpyrazole-4-carboxylate A solution of ethyl 5-amino-l-methylpyrazole-4-carboxylate (5 g, 29.6 mmol) in diethyl malonate (9 mL, 59.2 mmol) was heated at 180C overnight, then for a further 6 h at 200C. After this time, the reaction mixture was cooled and concentrated in vacuo, then purified by normal phase chromatography (Si02, 50% EtO Ac\/heptane to 100% EtO Ac), to yield the title compound (4.12 g, 49%) as a pale yellow oil that crystallised on standing. deltaEta (CDC13) 9.70 (br s, 1H), 7.79 (s, 1H), 4.27 (2 x q, J 6.8 Hz, 4H), 3.75 (s, 3H), 3.50 (s, 2H), 1.32 (2 x t, J 7.4 Hz, 6H).<\/p>\n
