Reaction Conditions

Reaction Steps

To a solution of 3-(tert-butyldiphenylsilyloxymethyl)-2,4-dichloroaniline (6.08 g) in acetic acid (15 ml) was added 2,5-dimethoxytetrahydrofuran (1.87 g). The mixture was stirred at 90° C. for 1 hour and evaporated under reduced pressure. The residue was purified by a silica gel column chromatography eluted with n-hexane-ethyl acetate to give 1-[3-(tert-butyldiphenylsilyloxymethyl)-2,4-dichlorophenyl]pyrrole (5.82 g) as a pale yellow oil.
