Procedure

To a solution of 6-Chloro-2,2-dimethyl-4-(trifluoromethyl)-2H-chromen-7-ol (0.66 g, 2.95 mmol), methyl 2-(4-(3-hydroxypropoxy)phenoxy)-2-methylbutanoate (1.0 g, 2.97 mmol) and triphenylphosphine (0.85 g, 3.24 mmol) in 25 mL THF is added diethyl azodicarboxylate (0.56 g, 3.21 mmol)(slight exotherm) and the reaction mixture is stirred at ambient temperature overnight (16 h). After concentrating under reduced pressure, the residue obtained is chromatographed over silica gel to provide methyl 2-(4-(3-((6-chloro-2,2-dimethyl-4-(trifluoromethyl)-2H-chromen-7-yl)oxy)propoxy)phenoxy)-2-methylbutanoate (0.99 g).
