1.13 g of NaH at 60% in oil, and then 2.35 ml of methyl iodide are added to a solution of 5 g of methyl 4-[[(tert-butoxycarbonyl)amino]methyl]benzoate in 150 ml of THF and the mixture is left to stir at AT overnight. The reaction mixture is concentrated under vacuum, the residue is taken up with a water/ice mixture, the mixture is extracted with EtOAc, the organic phase is dried over Na2SO4, and the solvent is evaporated off under vacuum. The residue is taken up with 80 ml of 2N hydrochloric ether, 1 ml of water is added, and the mixture is left to stir at AT overnight. The reaction mixture is concentrated under vacuum, the residue is taken up with a 5% NaHCO3 solution, the mixture is extracted with DCM, the organic phase is dried over Na2SO4, and the solvent is evaporated off under vacuum. 2.2 g of the expected compound are obtained.
