methyl 2-(1-methoxy-1-oxopropan-2-yl)oxybenzoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a mixture of 2-(6-Hydroxy-naphthalen-2-yl)-propionic acid methyl ester 6 (150 g, 652 mmol), anhydrous K2CO3 (480 gr, 3.473 mol) and sodium iodide (22.5 grams, 150 mmol) in anhydrous acetone (2000 ml) was added methyl 6-bromohexanoate (216 g, 1.033 mol) and refluxed for 60 hours. Acetone was distilled off and water (1500 ml) was added. Crude 9 was extracted into ethyl acetate, dried over Na2SO4, distilled and purified by column chromatography on silica gel using hexane as eluant to give pure 2 (130 g, 55.6%) as a light yellow syrup. The structure was confirmed with NMR. refluxed for 60 hours Acetone was distilled off water (1500 ml) was added Crude 9 was extracted into ethyl acetate dried over Na2SO4 distilled purified by column chromatography on silica gel
