Hydrochloric Acid → HCID 57871420, compound

Participants

Reaction Steps

Cool a CH2CL2 (30 mL) solution of 7-(1-ethyl-11-hydroxypropyl)naphthalen-2-ol (0.97 g, 4.2 mmol) and pyridine (1.3 mL, 16.3 mmol) with an ice bath. Treat the cooled solution dropwise with trifluoromethanesulfonic anhydride (1.0 mL, 6.1 mmol). Remove the cooling bath and stir the mixture for 1.5 h at RT. Quench the reaction with ice water. Dilute the reaction mixture with EtOAc and water (100 mL each) and acidify to pH 1 using 0.1N HCl. Dry the organic layer over Na2SO4, filter and concentrate the filtrate. Purify by radial silica gel (2:98 to 10:90 EtOAc:hex) to give the title compound as a colorless oil (1.46 g, 66%). MS (ES) m/e 377 (M-NH4).
