Procedure
Benzotriazole (6 g, 50 mmol) and N-methylbenzylamine (10.57 ml, 55 mmol) were dissolved in methanol (MeOH) (25 ml) followed by drop wise addition of formaldehyde (4.9 ml, 37% in H2O). The resulting mixture was heated at 50° C. for 15 h and cooled to ambient temperature. It was then diluted with diethyl ether (Et2O) (100 ml), washed with saturated sodium chloride aqueous solution (brine) (2×70 ml) and dried over magnesium sulfate (MgSO4) and concentrated. Upon further drying under reduced pressure, the material solidified to afford the depicted compound (13.2 g, 85%).
