Yield:13906-26-8 740 mg

Reaction Conditions:

with trichlorophosphate at 90;

Steps:

3.2 The second step, the synthesis of intermediate 9

Intermediate 8 (1 g, 3.8 mmol) was added to POCl₃, heated at 90 °C, TLC detected the disappearance of the raw materials, cooled to room temperature, the reaction solution was slowly poured into ice water, and filtered under reduced pressure to obtain 740 mg of white solid with a yield of 70 %, melting point 156-158.
