reported as an efficient catalyst in the presence of 5 mol % of LiOtBu for the N-methylation of amines using methanol as the methylating agent at moderate conditions, following hydrogen borrowing strategy. This simple catalyst system provides selective N-monomethylation of substituted primaryanilines and sulfonamides as well as N,N-dimethylation of primary aliphatic amines in excellent yields at 40–100
