In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 4152-90-3, name is (3-Chlorophenyl)methanamine belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Application In Synthesis of (3-Chlorophenyl)methanamine
STEP7 Preparation of N-(3-chlorobenzyl)-3-((3aR,4S,6aS)-2,2-dimethyltetrahydrothieno[3,4-d][1,3]dioxol-4-yl)imidazo[1,2-a]pyrazin-8-amine A mixture of 8-chloro-3-((3aR,4S,6aS)-2,2-dimethyltetrahydrothieno[3,4-d][1,3]dioxol-4-yl)imidazo[1,2-a]pyrazine (500 mg, 1.60 mmol), (3-chlorophenyl)methanamine (0.236 mL, 1.92 mmol) and DIPEA (0.700 mL, 4.01 mmol) in i-BuOH (8.0 mL) was subjected to microwave irradiation at 170° C. for 4 h. (The reaction was repeated 4 times in same scale). The combined reaction mixture was cooled to room temperature, diluted with EtOAc and washed with water and brine. The separated organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by column chromatography on NH-SiO2 (Hexanes:EtOAc=1:1) to give N-(3-chlorobenzyl)-3-((3aR,4S,6aS)-2,2-dimethyltetrahydrothieno[3,4-d][1,3]dioxol-4-yl)imidazo[1,2-a]pyrazin-8-amine (2.40 g, 90percent) as a yellow oil. 1H-NMR (CDCl3, 400 MHz): delta 7.44 (d, J=4.8 Hz, 1H), 7.39-7.40 (m, 2H), 7.26-7.25 (m, 4H), 6.32-6.24 (m, 1H), 5.10-5.05 (m, 2H), 4.78 (d, J=6.4 Hz, 2H), 4.55 (s, 1H), 3.05-3.04 (m, 2H), 1.60 (s, 3H), 1.38 (s, 3H).
The synthetic route of 4152-90-3 has been constantly updated, and we look forward to future research findings.
