Example No. 149Preparation of (4 , 5 -Dimethyl-thiazol-2-yl) – (8-methoxy-2H- pyrazolo [3 , 4-c] quinolin-4 -yl) -amine4 , 5-dimethylthiazol-2 -amine (0.4 mmol 2 eq. , ) was dissolved in THF (dry, 3mL) in a microwave vial (2-5mL) LiHMDS 2M in THF(0.6 mmol 4eq.) was added. The mixture was stirred for 20 min at r.t. and then added to a solution of 4-chloro-8-methoxy-2-(4 -methoxybenzyl) -2H-pyrazolo [3 , 4-c] quinoline (0.16 mmol, leq.) in pyridine (2mL) . The reaction mixture was irradiated in a microwave reactor for 20 min at 200 C. The reaction mixture was evaporated and used without further purification. The residue was dissolved in TFA (3mL) . The reaction mixture was irradiated in a microwave reactor for 5 min at 140C. The reaction mixture was concentrated and purified by semi- preparative HPLC-MS and freeze dried from water/t-BuOH 4/1. exact mass: 325.1205 g/molHPLC-MS: analytical method Brt: 2.397 min – found mass: 326.1 (m/z+H), 2289-75-0

Analyzing the synthesis route of 2289-75-0

2289-75-0 4,5-Dimethylthiazol-2-amine 73238, athiazole compound, is more and more widely used in various.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2289-75-0,4,5-Dimethylthiazol-2-amine,as a common compound, the synthetic route is as follows.

A mixture of 4,5-dimethylthiazol-2-ylamine (1.0 g, 7.8 mmol) and (2-bromo-ethoxy)benzene (1.9 g, 9.4 mmol) were heated neat to 85 0C for 19 hours. The mixture was cooled to ambient temperature and the residue was crystallized from isopropanol. The solid was collected by filtration and dried under vacuum to afford 1.3 g (50%) of the title compound. MS (DCIZNH3) mZz 249 (M+H)+, 2289-75-0
