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. 4214-72-6, name is N-Isopropylpyrimidin-2-amine. A new synthetic method of this compound is introduced below., HPLC of Formula: C7H11N3
General procedure: All 1-substituted 2-hydroxy-2-aryl-2,3-dihydro-imidazo[1,2-a]pyrimidinium salts were synthesized by using previously described protocols.41 A general procedure is described below (with compound 79 as an example): In a 30 mL microwave vial were successively brought acetonitrile (15 mL), N-(1,3-benzodioxol-5-ylmethyl)pyrimidin-2-amine (1.15 g, 5 mmol), 4-fluorophenacylbromide (1.3 g, 6 mmol, 1.2 equiv), and a catalytic amount of4-dimethylaminopyridine (6 mg, 0.05 mmol). The reaction tube was sealed and irradiated in a microwave reactor at a ceiling temperature of 80 C at 150 W maximum power for 30 min. After the reaction mixture was cooled with an air flow for 15 min, the precipitate was washed with acetone (25 mL), ether (20 mL) and dried in vacuum to afford 79 (1.98 g, 89% yield) as a white powder.
