    • 3b: A mixture of diethylphosphonoacetic acid (620 mg, 3.0 mmol), N-cyclohexylcarbodimide, N′-methyl polystyrene (5.0 g, 9.6 mmol) and HOBt (450 mg, 3.3 mmol) in N,N-dimethylacetamide/dichloromethane (1:1, 60 mL) was shaken at room temperature for 15 min. 4-(Dimethylamino)butyl amine (570 mg, 4. 9 mmol) in N,N-dimethylacetamide/dichloromethane (1:1, 10 mL) was added and the resulting mixture was shaken at room temperature for 18 h. Trisamine polystyrene (5.0 g, 20 mmol) was added and the resulting mixture was shaken at room temperature for 6 h. The reaction solution was collected by filtration. The resin was washed with dichloromethane (2×10 mL). The combined filtrate was concentrated in vacuo. The residue 0.89 g (100%) was used without purification.

    • 3a (28 mg, 0.1 mmol) in anhydrous THF (Aldrich, 1.5 mL) was added LDA (Aldrich, 2.0 M in heptane/THF/ethylbenzne, 0.25 mL, 0.5 mmol) at room temperature. After 30 min, 2-(3-chlorophenylthio)benzaldehyde (20 mg, 0.08 mmol) in anhydrous THF (0.75 mL) was added. The reaction mixture was stirred at room temperature for 1 h and quenched with water (0.3 mL). The reaction mixture was concentrated. The residue was purified by preparative HPLC on a Waters Symmetry C8 column (25×100 mm, 7 μm particle size) using a gradient of 10% to 100% acetonitrile: 0.1% aqueous TFA over about 8 min (10 min run time) at a flow rate of 40 ml/min to provide 21 mg (54%) of the desired product, 4a (Table 1, entry 4) as a trifluoroacetic acid salt.
