3,4-dihydro-2H-pyran → HCID 22054525, compound

Participants

Reaction Steps

A solution of (4-chloro-2,6-dimethyl-quinolin-7-yl)-methanol (example 59c, 300 mg, 1.35 mmol), 3,4-dihydro-2H-pyran (342 mg, 4.06 mmol), and pyridinium toluene-4-sulfonate (374 mg, 1.49 mg) in dichloromethane (3 mL) and toluene (3 mL) was stirred at r.t. for 3 d, then partitioned between ethyl acetate and water. The organic layer was washed with brine, dried (MgSO4), and evaporated. Flash chromatography (SiO2, hexane/ethyl acetate gradient) afforded the title compound (243 mg, 59%). White solid, ISP-MS: m/e=306.3 ([M+H]+).
