Embodiment 1
[0109] 4-(2-chloro-phenyl)-2-(2-[(5-{7-[2-(4-fluoro-phenyl)-5-isopropyl-3-phenyl-4-phenyl Carbamoyl-pyrrol-1-yl]-3,5-dihydroxy-heptanoyloxymethyl}-2-oxo-[1,3]dioxol-4-ylmethyl)-amino ]-ethoxymethyl}-6-methyl-1,4-dihydro-pyridine-3,5-dicarboxylic acid 3-ethyl ester 5-methyl ester
[0110] At 5°C, a solution of 4,5-bis(bromomethyl)-1,3-dioxol-2-one (10g, 36.8mmol) in ethyl acetate (10ml) was added dropwise to Atorval In a mixture of statin (7.45g, 12.9mmol), potassium bicarbonate (3g) and sodium iodide (0.05g) in ethyl acetate (60ml) and N,N-dimethylformamide (20ml), the mixture was stirred at room temperature The mixture was left for 8 hours. Cold water (30ml) was added with stirring and the organic phase was separated, washed with 5% aqueous sodium chloride and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography to produce atorvastatin 5-bromomethyl-2-oxo-1,3-dioxol-4-yl)methyl ...
Embodiment 2
[0112] 4-(2-Chloro-phenyl)-2-(2-{7-[2-(4-fluoro-phenyl)-5-isopropyl-3-phenyl-4-phenylcarbamoyl- Pyrrol-1-yl]-3,5-dihydroxy-heptanoyloxymethoxycarbonylamino}-ethoxymethyl)-6-methyl-1,4-dihydro-pyridine-3,5-dicarboxy Acid 3-ethyl ester 5-methyl ester
[0113] Chloromethyl chloroformate (2.85g, 22mmol) was added to a solution of amlodipine (10.5g, 20mmol) and pyridine (1.6g) in 300ml of chloroform, which was cooled in an ice bath. The reaction mixture was stirred at room temperature for 16 hours, washed with water, dried (anhydrous sodium sulfate) and concentrated under reduced pressure. The residue was dissolved in a solution of calcium salt of atorvastatin (10.75 g, 0.018 mol) in dimethylformamide (50 ml), and the reaction mixture was heated at 80°C for 20 hours. Dimethylformamide was removed in vacuo and the residue was triturated with chloroform-hexane to produce the title compound of Example 2.
