Reaktionsschritte

To a solution of 4.5 g of ethyl 4,4,4-trifluoro-3-methyl-2-butenoate in 50 ml of tetrahydrofuran was added dropwise 48 ml of diisobutylaluminum hydride (1.02M solution in hexane) under ice-cooling. The reaction mixture was stirred at the same temperature for 2 hours. To the reaction mixture was added diluted sulfuric acid and then extracted with t-butyl methyl ether. The organic layer was dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure to obtain crude 4,4,4-trifluoro-3-methyl-2-buten-1-ol.
