Procedure

A flask was charged with potassium tert-butoxide (58 mmol) and 63 mL of tert-butyl alcohol. The mixture was stirred until a solution was formed, and a solution of the appropriate benzophenone (50 mmol) in 35 mL of tert-butyl alcohol added dropwise over 15 min. The reaction mixture was stirred for 1 hr, and the neat isoamyl nitrite (75 mmol) added over five min. The reaction mixture was monitored for completion and then diluted with 100 mL of heptanes. The resulting solid (38 mmol) was collected via suction filtration and dried to a constant weight under vacuum. Procedure was adapted from: Hagedorn et al., Chem. Ber., 98:193 (1965).
