Reaction Steps

Di-isopropyl azodicarboxylate (0.21 ml) was added to a stirred mixture of N-[2-methyl-5-(3-morpholinobenzamido)phenyl]4-hydroxybenzamide (0.15 g), 3-hydroxytetrahydrofuran (0.31 g), triphenyl phosphine (0.275 g) and methylene chloride (5 ml) which had been cooled to 5° C. The resultant mixture was stirred at ambient temperature for 18 hours. The mixture was poured onto a pre-wetted (methylene chloride) ion-exchange column (isolute SCX 5 g column from International Sorbent Technology Limited) and eluted in turn with methylene chloride (40 ml), with methylene chloride (40 ml) containing 20% methanol and with methylene chloride containing 20% methanol and 3% of a saturated aqueous ammonium hydroxide solution. The product so obtained was further purified by column chromatography on silica using a 4:1 mixture of ethyl acetate and methanol as eluent. There was thus obtained the title compound as a solid (0.52 g); Mass Spectrum: M+H+ 502.
