Product 1

HCID 582577564-[3-(2-Chloro-quinolin-6-ylsulfanyl)-phenyl]-tetrahydro-pyran-4-carbonitrile

Conditions

Temperature
90 °C

Procedure

5g (4.52 g, 12.5 mmol) was dissolved in phosphorus oxychloride (23 mL) and heated to 90° C. for 1 hour. The reaction was cooled to room temperature, and ice was added slowly, followed by EtOAc and NaHCO3. The aqueous layer was extracted with CH2Cl2 twice, and the combined organic layers were dried over MgSO4, filtered, and concentrated to give the desired product, 5h.
