To further investigate the importance and practical utility of this method,a gram-scale reaction of 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline(1a,1.1 g,5.0mmol)and benzaldehyde(2a,0.6 g,6.0 mmol)was performed under the optimal reaction conditions.As a result,the reductive amination reaction proceeded smoothly to afford N-benzyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline(3a)in 70%isolated yield(Scheme 2).
