Reference of 10269-01-9, These common heterocyclic compound, 10269-01-9, name is (3-Bromophenyl)methanamine, its 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.
Step 3. Preparation of (2R,3R,4R)-2-(6-(3-bromobenzylamino)-2-chloro-9H-purin-9-yl)tetrahydrofuro-3,4-diol After dissolving (2R,3S,4S)-2-(2,6-dichloro-9H-purin-9-yl)tetrahydrofuro-3,4-diol (1 eq.) prepared in the step 2 and 3-bromobenzylamine (1.5 eq.) in ethanol (5 ml) at room temperature, the reaction mixture was stirred at room temperature for 2-3 h. After completion of the reaction, the reaction mixture was concentrated under reduced pressure, and the residue was subjected to silica gel column chromatography using a dichloromethane:methanol mixed solvent (20:1, v/v) as an eluent to obtain the target compound (0.12 g, 82%). mp 181.5-181.7 C.;
Statistics shows that (3-Bromophenyl)methanamine is playing an increasingly important role. we look forward to future research findings about 10269-01-9.
