Reaction Steps

To a solution containing 38.4 g of 3,4-dichloronitrobenzene in 150 ml of DMSO was added 17.3 g of cyclopropylmethanol. This solution was stirred during the dropwise addition of 9.2 g of sodium hydroxide dissolved in 10 ml of water. This addition was exothermic to 45° C. The mixture was stirred and heated to 75°-80° for 18 hours, than poured over ice water and filtered. The filter cake was recrystallized from methanol to yield 27 g (59%) of light tan solid, melting point, 42°-44° C.
