반응 단계
The title compound of step 1 (5.30 g, 19.63 mmol), POCl3 (18.06 g, 117.78 mmol), (Me)4NCl (3.23 g, 29.47 mmol) in dry CH3CN (60 mL) was refluxed for 12 h. The mixture was poured into ice-water (50 mL) and subjected to EA extractive work up. Concentration under vacuum gave impure title compound (4.0 g), which was carried on to the next step.
