Argon was bubbled through a mixture of BSTFA (0.3 mL; 1.3 mmol), benzyl bromide (0.1 mL; 0.7 mmol), and CH2Cl2 (1.5 mL) for 10 minutes. 2-({6-[(tert-Butoxycarbonyl)amino]pyridin-3-yl}methyl)-3-ethoxy-3-oxopropylphosphinic acid (50 mg; 0.13 mmol) was added, and the reaction mixture was refluxed under argon for 1 h. The solution was concentrated to afford 0.13 g of crude benzyl[2-({6-[(tert-butoxycarbonyl)amino]pyridin-3-yl}methyl)-3-ethoxy-3-oxopropyl]phosphinic acid.
