Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Synthesis of [18F]-FCPHA was performed using the following method. PCC (pyridinium chlorochromate; 24.8 g, 115.2 mmol) was slowly added in portions to a solution of 6-benzyloxy-1-hexanol (20 g, 96 mmol) in 200 ml of methylene chloride at room temperature (25° C., RT). The black mixture was stirred for 2 hours, and filtered through 50 g of silica gel. The solvent was removed and the crude oil was separated chromatographically on silica gel using a mixture of hexane:ethyl acetate at a ratio of 90:10. This yielded the aldehyde equivalent, 6-benzyloxy-1-hexanal, at a scale of 14 g (70%). filtered through 50 g of silica gel The solvent was removed the crude oil was separated chromatographically on silica gel using a mixture of hexane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of alcohol (22, 6-(benzyloxy)hexan-1-01) dissolved in dry DCM, Tempo free radical (0.1 equiv), iodobenzenediacetate (1.1 equiv) were added and stirred at 25° C. On completion of the reaction (by checking TLC), it was quenched with dilute solution of Na2S2O3. The organic layer was extracted in DCM, washed with brine, dried over anhydrous Na2SO4. The solvent was removed in vacuum concentrated and subjected for chromatographic separation. The eluent was allowed to come in a solution of pet ether:EtOAC=95:5 as a colorless liquid. 1H NMR (CDCl3, 200 MHz): δ 9.8 (s, 1H), 7.2-7.4 (m, 5H), 4.5 (s, 2H), 3.5 (t, 2H), 2.4 (t, 2H), 1.6 (m, 4H), 1.4 (m, 4H); 13C NMR (CDCl3, 50 MHz): δ 202.75, 138.50, 128.40, 127.68, 127.50, 72.95, 70.03, 43.86, 29.53, 25.85, 21.91.
