Procedure
A suspension of 1-amino-3-methylpyridin-2(1H)-iminium-2,4,6-trimethylbenzenesulfonate (630 mg, crude product from the previous step, 1.95 mmol), methyl 2-chloroacetate (423 mg, 3.90 mmol) and potassium carbonate (540 mg, 3.9 mmol) in EtOH (10 mL) was stirred at 80° C. for 4 h. After cooled to room temperature, the reaction mixture was concentrated and the residue was purified by silica gel column chromatography (eluting with 25% v/v EtOAc in PE) to give the title compound (95 mg, yield 27%). ESI MS: m/z 182, 184 [M+H]+.
