Phthalimide → 2-((-2-(5-(4-Fluorophenyl)-2-methylthiazole-4-carbonyl)octahydrocyclopenta[c]pyrrol-1-yl)methyl)isoindoline-1,3-dione

Participants

Reaction Steps

A solution of (5-(4-fluorophenyl)-2-methylthiazol-4-yl)(1-(hydroxymethyl)hexahydrocyclopenta[c]pyrrol-2(1H)-yl)methanone (1 eq), phthalimide (2 eq) and triphenylphosphine (3 eq) in THF (56 mL) was cooled to 0° C. and added with DIAD (5 eq) dropwise. The resulting suspension was allowed to warm to rt gradually and stirred overnight, concentrated in vacuo to a brown oil. The reaction mixture was diluted with EtOAc and washed with water, brine, dried (MgSO4), and concentrated. The crude residue was purified by chromatography on silica gel (EtOAc/hex) to give the title compound as a clear oil. MS (ESI) 490.4 (M+H).
