512 mg (2.41 mmol, 1.5 eq) of sodium triacetoxyborohydride are added to a solution of 200 mg (1.61 mmol, 1 eq) of 6-methoxypyridin-2-ylamine (starting material 1) and 236 mg (2.41 mmol, 1 eq) of 2-hydroxybenzaldehyde (starting material 2) in 20 ml of tetrahydrofuran. The solution is stirred at room temperature for 48 h. It is evaporated and the residue is taken up in 100 ml of dichloromethane and then extracted with a saturated aqueous solution of ammonium chloride. The aqueous phase is extracted twice with dichloromethane. The organic phases are combined and dried over sodium sulphate. The residue is chromatographed on silica gel (5/95 ethyl acetate/heptane). 2-[(6-methoxypyridin-2-ylamino)methyl]phenol is obtained in the form of a white solid. Melting point=103° C.
