実験手順

To a solution of N-{4-[4-iodo-5-(1H-1,2,4-triazol-3-yl)-1,3-oxazol-2-yl]-5-methylpyridin-2-yl}acetamide (6.2 g, 15 mmol) in DMF (60 mL) was added DIEA (4.0 mL, 23.0 mmol). The reaction mixture was allowed to stir at rt for 2 h and then SEM-Cl (4.1 mL, 23.0 mmol) was added. The reaction mixture was allowed to stir at rt overnight and then concentrated. The residue was purified by column chromatography to give N-{4-[4-iodo-5-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,4-triazol-3-yl)-1,3-oxazol-2-yl]-5-methylpyridin-2-yl}acetamide (2.7 g) plus another SEM regioisomer (1.2 g).
