[0161]
[0162] Step 1) (2R,3R,4S,5R,6R)-2-(acetoxymethyl)-6-(2,2,2-trichloro-1-iminoethoxy) tetra Synthesis of Hydrogen-2H-pyran-3,4,5-triyltriacetate
[0163]
[0164] (2R,3R,4S,5R)-2-(Acetoxymethyl)-6-hydroxytetrahydro-2H-pyran-3,4,5-triyltriacetate (4.0g, 11.5mmol) , trichloroacetonitrile (11.5mL, 115mmol), 4A molecular sieves (5g) and dichloromethane (80mL) were added to a 250mL single-necked round bottom flask, stirred in an ice bath under nitrogen protection for 1 hour, and then DBU (0.35mL, 2.3mmol ), stirred and reacted in an ice bath for 1 hour; the reaction was stopped, filtered, and the filtrate was collected and spin-dried under reduced pressure, separated and purified by column chromatography (petroleum ether / ethyl acetate (v / v)=4 / 1) to obtain the title compound as ...
Embodiment 2
[0186]Example 2 4-(3-chloro-4-(3-(3-fluoro-4-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl Synthesis of base)tetrahydro-2H-pyran-2-yl)oxy)phenyl)urea)phenoxy)-7-methoxyquinoline-6-carboxamide
[0187]
[0188] Step 1) (2R,3R,4S,5R,6S)-2-(Acetoxymethyl)-6-(2-fluoro-4-nitrophenoxy)tetrahydro-2H-pyridine Synthesis of pyran-3,4,5-triyltriacetate
[0189]
[0190] The title compound of this step was prepared by referring to the method described in step 2 of Example 1, that is, (2R,3R,4S,5R,6R)-2-(acetoxymethyl)-6-(2,2,2-trichloro -1-iminoethoxy)tetrahydro-2H-pyran-3,4,5-triyltriacetate (1.0g, 2.03mmol), 2-fluoro-4-nitro-phenol (382mg, 2.43mmol), 4A molecular sieve (1.2g) and boron trifluoride diethyl ether (0.316mL, 2.43mmol) were prepared by reacting in dichloromethane (16mL), and the crude product was separated and purified by silica gel column chromatography (petroleum ether / ethyl acetate (v / v)=2 / 1) afforded the title compound as a white solid (0.65 g, 65.7%)....
