73006-78-7, The chemical industry reduces the impact on the environment during synthesis 73006-78-7, name is 5-Chloro-[1,1′-biphenyl]-2-amine, I believe this compound will play a more active role in future production and life.
A mixture of the product from step (i) (0.94g), sodium acetate (0.5g) and tert- butylbromoacetate (0.6ml) in ethanol (20ml) was heated under reflux for 5h. A further porton of sodium acetate (Ig) and tert-butylbromoacetate( 1.2ml) was added and the mixture heated under reflux overnight. The solvent was evaporated under reduced pressure and the residue partitioned between ethyl acetate and water, the organic layer was washed with water, dried, and the solvent evaporated under reduced pressure. The residue was purified by chromatography on silica eluting with 5% ethyl acetate/isohexane, yield 0.775g. MS: APCI (-ve) 260 (M-l-tBu)
