Reaction Steps
5-Bromo-2-{[methoxycarbonylmethyl-(toluene-4-sulfonyl)-amino]-methyl}-6-oxo-1-(tetrahydro-pyran-4-ylmethyl)-1,6-dihydro-pyridine-3-carboxylic acid methyl ester (411 mg, 0.70 mmol) was dissolved in 15 mL of MeOH and placed in ice bath. NaOMe solution (0.5 mL, 2.11 mmol, 4.375 M in MeOH) was added and the mixture was stirred for 16 h at r.t. 1 M HCl was added to acidify the mixture, and brine was added until precipitate appeared. The resulting suspension was extracted with CH2Cl2. The organic layer was dried over MgSO4 and concentrated. The crude product was purified by silica gel chromatography (0-4% MeOH/CH2Cl2) to give 200 mg of the title compound as a light yellow solid. MS: (+) m/z 397.21, 399.16 (M+1, 79/81Br).
