Procedure:
To a suspension of 4 g (0.16 mol) of sodium hydride in 200 ml of DMF 20 at 0° C. was added 10 g (0.145 mol) of 1,2,4-triazole in 75 ml of DMF dropwise over a period of 30 minutes, and the mixture was allowed to warm to room temperature and stirred for 1 h. The above mixture was cooled to 0° C., 25 g (0.16 mol) of p-methoxybenzyl chloride was added, the mixture was allowed to warm to room temperature, and stirred for 16 h.

Procedure:
The photo-bleachable compound expressed by the structural formula (II-14) was prepared in the following manner. Thus, a reaction mixture was prepared by dissolving 6.81 g (0.05 mole) of p-anisaldehyde and 4.66 g (0.05 mole) of γ-picoline in 10.21 g (0.10 mole) of acetic anhydride and the mixture was heated under reflux for 16 hours to effect the reaction. After acetic acid and the unreacted acetic anhydride were evaporated from the reaction mixture, the residual reaction mixture was poured into water so that a crystalline material was precipitated therein. The reaction mixture was filtered and the collected precipitates were washed with water. Recrystallization of the precipitates from a mixture of methyl alcohol and water gave 5.80 g of 4-[2-(4-methoxyphenyl)ethenyl]pyridine, the yield of which was 55% of the theoretical value.
