Procedure

To a stirred suspension of t-butyl hydrazine hydrochloride (0.02 mol) in toluene (20 ml) and aqueous hydroxide (5 ml of 50% solution) at room temperature was added pyrenonecarbonyl chloride (0.01 mol). After stirring the reaction mixture for 20 minutes, ether and hexane were added and the solid product was filtered and washed with water. The solid product (0.5 g) was stirred in toluene (10 ml) and aqueous sodium hydroxide and m-toluoyl chloride (0.8 g) was added dropwise. After stirring for 5 hours, hexane and ether were added and the solid product filtered and air dried.
