OCH3 OH from One route to the synthesis of HO and CH,CH2MgBr is to 1) protect the ketone as an acetal, 2) reduce the ester to an alcohol, 3) hydrolyze the acetal back to the ketone, 4) protect the alcohol as a TMS ether, 5) react the ketone with the Grignard reagent followed by acidic workup to give the desired product. A second route to the desired product would start with the selective reduction of only the ketone to an...
