With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13743-09-4,2-Methyl-5-phenylthiazole-4-carboxylic acid,as a common compound, the synthetic route is as follows.,13743-09-4
(S)-7-Methyl-2-(2-methylpyrrolidin-2-yl)-1 H-benzo[d]imidazole hydrochloride (27; 25.2 mg, 0.1 mmol) is dissolved in DCM (0.2 ml) and DIPEA (0.072 ml, 0.42 mmol) is added, followed by the addition of a solution of 2-methyl-5-phenylthiazole-4-carboxylic acid (28; 22 mg, 0.1 mmol), HATU (40 mg, 0.105 mmol) and DIPEA (80 mg, 0.62 mmol) in 0.5 ml DMF. Stirring is continued at RT for 16 h. The reaction mixture is diluted with DCM / MeOH = 1/1 (1 ml) followed by the addition of PL-HCCVresin (213 mg, 0.4 mmol) and stirring is continued for 2 h. The resin is filtered off, the solvent is evaporated under reduced pressure and the product is purified by preparative HPLC to give (S)-(2-methyl-2-(7-methyl-1 H- benzo[d]imidazol-2-yl)pyrrolidin-1 -yl)(2-methyl-5-phenylthiazol-4-yl)methanone (Ex. 5.1 ) as a colorless powder. LC-MS: tR = 1 .19 min; [M+H]+ = 417.31.
The synthetic route of 13743-09-4 has been constantly updated, and we look forward to future research findings.
