a Effect of base to precursor ratio on fluorination efficiency and fluorination yield (n = 1 for each data point). Syntheses carried out at 80 °C for 5 min with 30 nmol or 60 nmol of precursor. b Effect of deprotectant (10 μL HCl) concentration on deprotection reaction at 90 °C for 3 min (n = 1 for each condition). Synthesis performed with 60 nmol precursor and 110 nmol TBAHCO3 at 90 °C for 5 min
