Some common heterocyclic compound, 41716-18-1, name is 1-Methyl-1H-imidazole-4-carboxylic acid, molecular formula is C5H6N2O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. category: imidazoles-derivatives
To a suspension of [1-METHYL-IMIDAZOLE-4-CARBOXYLIC ACID (11.] 4g, 90 [MMOL)] in THF (500ml) at [0°C,] was added drop-wise a solution of lithium aluminium hydride [(1 M] in THF, [117ML,] 117 [MMOL)] and the mixture was stirred at room temperature overnight and then at [50°C] for 1 hour Water (3 [ML)] was added followed by [NA2SO4] and the mixture was filtered through [CELITETM.] The filtrate was concentrated under reduced pressure to afford the title compound as a solid [(8G,] 78.95percent) ;’H NMR (300 MHz, [CDCI3)] 6 ppm: 7.25 (s, 1 H), 6. 7 (s, 1H), 5.25 (m, 1H), 4.4 (s, 2H), 3.45 (s, 3H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 41716-18-1, its application will become more common.
