Brief introduction of 1-Methyl-1H-imidazole-4-sulfonyl chloride

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Methyl-1H-imidazole-4-sulfonyl chloride, its application will become more common.

Application of 137049-00-4,Some common heterocyclic compound, 137049-00-4, name is 1-Methyl-1H-imidazole-4-sulfonyl chloride, molecular formula is C4H5ClN2O2S, 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.

3. Synthesis of (1-(1-Methyl-1H-Imidazol-4-ylsulfonyl)Piperidin-4-yl)(Phenyl)Methanone, 4; To a solution of 4-benzoylpiperidine hydrochloride (1.50 g, 6.64 mmol) and DIPEA (2.74 mL, 15.3 mmol) in CH2Cl2 (35 mL) was added 1-methylimidazole-4-sulfonyl chloride (1.31 g, 7.31 mmol) and stirred for 18 h. The reaction was washed with 2 N NaOH (30 mL), dried over MgSO4 and concentrated under vacuum to afford 4 as a white solid (2.05 g, 93%); 1H-nmr (400 MHz, CDCl3) delta 7.81-7.78 (m, 2H), 7.52-7.36 (m, 5H), 3.86-3.78 (m, 2H), 3.71 (s, 3H), 3.26-3.17 (m, 1H), 2.82 (td, J=11.0, 3.0 Hz, 2H), 1.92-1.84 (m, 4H); m/z 334.0 [M+H].

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Methyl-1H-imidazole-4-sulfonyl chloride, its application will become more common.
