To a solution of methyl 3-(((tert-butoxycarbonyl)(tetrahydro-2H-pyran-4-yl)amino)methyl)benzoate (550 mg, 1.57 mmol) in MeOH (5 mL) was added aqueous of NaOH (2.0 mL, 40% w/w). The mixture was stirred at 25° C. for 4 h. The reaction solution was concentrated, and the residue was dissolved in water and adjusted pH to 5-6 with 2N of HCl and extracted with EA. The organic layer was concentrated to give the desired product (300 mg, Yield 57%). LCMS (m/z): 336.1 (M+1).
