7. 3 (MeOTf) at room temperature. The light yellow solution becomes orange and the greenish-yellow fluorescence of PNBT is replaced by an orange-reddish color under long-wavelength UV light. Further aliquots of MeOTf were added in 10 h intervals until 25 equiv of MeOTf was added. After 60 h, solvent and excess MeOTf were removed under vacuum. The product was analyzed for F (10.5%), corresponding to 55% methylation. With 4 equiv of MeOTf and a 10 h reaction time, the F analysis was 1.50%, corresponding to 6% methylation, whereas heating the PNBT solution with a large excess of MeOTf for 3 days gave 100% methylation (16% F).
