Procedure

Methyltriazole M13.6 (2.78 g, 5.61 mmol) was dissolved in 50 mL of EtOAc, and nitrogen was bubbled through the solution for 5 minutes. 1 g of palladium on carbon (5 wt. %, wet contains 50% water) was added, and a hydrogen balloon was attached. After 8 hours, the mixture was filtered through a plug of silica with 10% MeOH in EtOAc. The organic layer was concentrated under reduced pressure and partitioned between ACN (100 mL) and hexane (50 mL). The ACN layer was washed with hexane (4×50 mL). The ACN layer was concentrated under reduced pressure to afford (S)-methyl 3-(4-hydroxyphenyl)-3-(2-methyl-2H-1,2,4-triazol-3-yl)propanoate M13 (1.30 g, 4.99 mmol) as a colorless oil. MS ESI (pos.) m/e: 262.4 (M+H)+.
