Procedure

To an ice-cooled solution of phenyl dichlorophosphate (2.83 g, 0.02 mol) in dry toluene (50 mL) is added triethylamine (2.02 g, 0.02 mol) followed by nonyl alcohol (2.89 g, 0.02 mol) in dry toluene (40 mL) dropwise. The reaction mixture is stirred in an ice bath for 2 hours and then filtered. To this filtrate are added triethylamine (2.02 g, 0.02 mol) and a solution of N-[2,6-bis(1-methylethyl)phenyl]-2-[phenylmethyl]amino-acetamide (Example V) (6.40 g, 0.02 mole) and the mixture is stirred at room temperature overnight. The reaction mixture is filtered and concentrated. Flash column chromatography and crystallization from ethyl acetate affords 3.8 g of the title compound; IR (KBr); 3285, 2961, 2925, 2858, 2367, 1684, and 1508. 1H NMR (250 MHz, DMSO)δ9.22 (1 H, s), 7.44-6.92 (13 H, m), 4.50-4.30 (2 H, m), 4.30-4.00 (2 H, m), 4.00-3.60 (2 H, m), 3.10-2.80 (2 H, m), 1.70-1.40 (2 H, m), 1.4-1.18 (12 H, m), 1.18-1.00 (12 H, d, J=7 Hz), 0.98-0.76 (3 H, m).
