Procedure

To a 15 ml round bottom flask charged with 2-tert-butyl-4-tert-butyldimethylsilyloxymethyl-5-(4-tert-butylbenzyl)thio-3(2H)-pyridazinone (2 g, 4.2 mmol) is added tetrabutylammonium fluoride solution (1M in THF, 21 ml, 21 mmol). The mixture is first stirred at room temperature for 5 hours and to it is added dichloromethane followed by water. The layers are separated and the organic layer is washed with water and dried. The organic layer is then concentrated and subjected to purification using silica gel flash chromatography (ethyl acetate/hexanes) to obtain the above compound.
