Reaction Steps

The [11C]MeI was trapped at 0° C. in a mixture of 2,4-dichloro-N-{[4-(3-hydroxypyridin-2-yl)-1-(propylsulfonyl)piperidin-4-yl]methyl}benzamide (0.25 mg) in DMF (0.2 mL) containing Cs2CO3 (1-2 mg). This mixture was transferred to a vial at 100° C. and heated for five minutes. The reaction was diluted with H2O (0.8 μL) and purified by HPLC (Waters C18 XTerra, 7.8×150 mm, 5 μm, 15 minutes linear gradient 20% MeCN:(95:5:0.1) H2O:MeCN:TFA to 90% MeCN @ 3 mL/min, product elutes at 8.5 minutes). The product fraction was collected in a heated round bottom flask attached to a rotary evaporator, the solvent was removed and the product was transferred to a vial using physiologic saline to give to give 65 mCi of [11C] 2,4-dichloro-N-{[4-(3-methoxypyridin-2-yl)-1-(propylsulfonyl)piperidin-4-yl]methyl}benzamide.
