Triphenylphosphine → HCID 58530768, compound

Participants

Reaction Steps

To a solution of (5Z)-5-({1-[4-chloro-2-(trifluoromethyl)benzyl]-1H-indazol-5-yl}methylidene)-3-hydroxy-1,3-thiazolidine-2,4-dione (Example 288; 0.044 mmol), 1-(2-hydroxyethyl)pyrrolidine (1.5 equiv.) and triphenylphosphine (1.5 equiv.) in THF (5 mL) was added DIAD (1.5 equiv.) and the resultant solution was stirred overnight at rt. The mixture was then concentrated in vacuo, and the residue was purified by reverse phase HPLC (MeCN/water/formic acid) to provide (5Z)-5-({1-[4-chloro-2-(trifluoromethyl)benzyl]-1H-indazol-5-yl}methylidene)-3-(2-pyrrolidin-1-ylethoxy)-1,3-thiazolidine-2,4-dione.
