Participants

Reaction Steps

To a solution of 3-t-butyldiphenyloxy-1-{4-[2-(t-butyldiphenylsilyloxy)-1-(t-butyldiphenylsilyloxymethyl)ethylcarbamoyl]-1,3-thiazol-2-yl}azetidine (3.19 g, 3.23 mmol) (obtained as described in Reference Example 39(3)) in anhydrous tetrahydrofuran (160 ml) was added a solution of 1.0M tetra-n-butylammonium fluoride in tetrahydrofuran (11.6 ml, 11.6 mmol) in an ice bath. The mixture was stirred in the ice bath for 2 hours. After checking the completion of the reaction, the reaction mixture was concentrated under reduced pressure. The residue was purified by chromatography on a silica gel column using ethyl acetate:methanol (9:1→8:2) as the eluant to afford 3-hydroxy-1-{4-[2-hydroxy-1-(hydroxymethyl)-ethylcarbamoyl]-1,3-thiazol-2-yl}azetidine (1.21 g, yield 100%) as a white solid.
