Procedure:
The title compound is prepared from 5-(1-benzyl-2-(pyridin-3-yl)-1H-imidazol-5-yl)-4-methyl-2-phenylthiazole (Example 71) in a similar manner as described in Tetrahedron Letters, 2008, 64(26), 6060-6072. In this case, 5-(1-benzyl-2-(pyridin-3-yl)-1H-imidazol-5-yl)-4-methyl-2-phenylthiazole in methanol is debenzylated by hydrogenation under an atmospheric pressure of hydrogen using a balloon with vigorous stirring for 70 h under reflux. The reaction mixture is filtered through Celite, filtered and concentrated under reduced pressure. The residue is chromatographed on silica to give the title compound.

Procedure:
To a suspension of NaH (60%, 20.4 g) in THF (dry) (250 mL) was added 2-chloroethanesulfonyl chloride (32.2 mL) at 0° C. and the mixture was stirred for 5 min at the same temperature.

Procedure:
To a solution of fumagillol (314 mg) in dichloromethane (5 ml) was added dropwise chloroacetyl isocyanate (160 mg) under ice cooling, followed by addition of dimethylaminopyridine (130 mg). The mixture was stirred at 0° C. for 2 hours. To this reaction mixture was added water and the mixture was extracted with dichloromethane. The organic layer was washed with saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was subjected to silica gel column chromatography. The eluate obtained with a mixture of n-hexane and ethyl acetate (3:1) was concentrated under reduced pressure to give colorless, powdery O-chloroacetylcarbamoylfumagillol (318 mg) (71% yield).
