Procedure

A mixture of compound XXII (1.5 g, 0.005 mol), triethylamine (1.41 g, 0.014 mol) and palladium on carbon (10% w/w) (0.45 g) in methanol (100 mL) was purged with nitrogen, and then shaken in a Par apparatus under an atmosphere of hydrogen gas (45 psi pressure) for 3 days. The mixture was purged with nitrogen, concentrated in vacuo to a volume of ca. 20 mL, diluted with water (50 mL) and ethyl acetate (100 mL). The biphasic mixture was filtered to remove the catalyst and the organic phase separated, rinsed with brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo to afford the titled compound XXIII as a white solid (0.64 g, 48% yield, crude): m.p. 181-182° C.; ESI/MS 289 (M+H) 287 (M−H).
