実験手順

A solution of (2-methylpyrimidin-5-yl)methanol (0.82 g, 6.6 mmol) in toluene (30 mL) and methylene chloride (40 mL) at 0° C. was treated with diphenylphosphonic azide (2.8 mL, 13 mmol) followed by 1,8-diazabicyclo[5.4.0]undec-7-ene (2.0 mL, 13 mmol) and stirred at 0° C. for 2 h. After being further stirred at rt for 16 h, the reaction mixture was diluted with water (50 mL) and methylene chloride (50 mL). The organic layer was separated and washed with brine, dried (Mg2SO4), filtered, and concentration. The residue was purified by silica gel column to yield a colorless oil.
