In a three neck flask kept under argon and containing 90 ml of CH2Cl2, 4-nitrooxybutanoic acid (800 mg, 5.3 mmol) prepared as described above was charged. Then PCl5 was added in one portion (1.25 g, 6.0 mmol) and the resulting mixture was stirred at room temperature. The reaction was checked by IR spectroscopy. After ca. 2 hours stirrer was removed and the reaction mixture was distilled under vacuum. The crude chloride (900 mg, 5.4 mmol) was used in the further steps without purification.
