    • In the series of N-TBDPS- and N-Boc-4-methyl-6-bromo-2-pyridone derivatives, we had seen that the 4-methyl group can be quantitatively alkylated with LDA/EtI. Similarly, a preliminary experiment with the TPDPS-protected 8 showed that alkylation with LDA/EtI at 0 °C provided selectively the 4-isobutyl derivative (data not shown).
