Participants

Reaction Conditions

Reaction Steps

11.4 g (0.05 mol) of bisphenol A (result of calculation of dipole moment based on MOPAC-97=2.1 debye) and 34.9 g (0.13 mol) of 5-naphthoquinone diazide sulphonyl chloride were dissolved in 400 g of 1,4-dioxane under a current of dry nitrogen, and then warmed to 40° C. To this there was added, dropwise, 13.1 g (0.13 mol) of triethylamine mixed with 40 g of 1,4-dioxane, and then naphthoquinone diazide compound (4) was obtained in the same way as in Synthesis Example 1. (As an average, 1.3 of the Q groups=5-naphthoquinone diazide sulphonyl groups and 0.7=hydrogen.)
