Participants

Reaction Steps

To a solution of 3-(1-(4-hydroxy-3-(methoxycarbonyl)phenyl)-5-phenyl-1H-pyrrol-2-yl)propanoic acid (40 mg, 0.109 mmol) in 2 ml anhydrous THF was added LiBH4 (2M in THF, 0.14 ml, 2.5 eq.) via a syringe at 0° C. The reaction mixture was stirred at rt for 4 hours. Mixture was quenched with saturated sol. NH4Cl, then acidified to pH=2 using 10% HCl solution. This was extracted several times using ethyl acetate. Combined organic layers were washed with brine, dried (Na2SO4) and concentrated. The crude was purified by preparative TLC using 1:1 ethyl acetate/hexane. 18 mg of 3-(1-(4-hydroxy-3-(hydroxymethyl)phenyl)-5-phenyl-1H-pyrrol-2-yl)propanoic acid was obtained, 47% yield.
