Yield:106-47-8 92%

Reaction Conditions:

with potassium carbonate;ammonium hydroxide in methanol at 60; for 21 h;

Steps:

General procedure for the synthesis of primary amines

General procedure: RGO/Cu NPs (25 mg), arylboronic acid (1.0 mmol), K2CO3(1.3 mmol), 25-28% aqueous ammonia (5 mmol) and methanol(4 mL) were added to a 50 mL round-bottomed flask. The reactionmixture was stirred under reflux conditions for the appropriatetime. After completion of the reaction as monitored by TLC, themixture was filtered, and the solvent of the filtrate was removedunder vacuum with the aid of a rotary evaporator. The residue waspurified by column chromatography on silica gel to afford the prod-uct. All products are known in the literature and the physical data(mp, IR, NMR) of the products were found to be identical with thosereported in the literature [36,37].
