Procedure
Lithium tert-butoxide (1M in hexanes, 178 mL, 0.178 mol) was added dropwise at room temperature to p-toluoyl chloride (25 g, 0.162 mol) in tetrahydrofuran (150 mL). The mixture was stirred at room temperature overnight and then diluted with water and extracted with ethyl acetate. The extract was washed with brine, dried (MgSO4), and evaporated to give product as an oil which crystallized on standing (31 g, 98%)
