    • note
    • The modifications consisted of: (i) no sodium bicarbonate was added to the reaction mixture; (ii) the reaction was finished in 2 min; and (iii) no sodium bisulfite was used in the work-up of the reaction. It is worth mentioning that under these conditions we did not observe oxidation of the N-benzyl group.
