Synthesis of [C-14]ABT-418, a cholinergic channel activator labeled at two sites on the isoxazole ring
[C-14]ABT-418, (8)-3-[C-14]methyl-5-[N-methyl-2-pyrrolidinyl][4-C-14]isoxazole hydrochloride, was labeled in two positions at maximum specific activity. Starting with 100 mCi of sodium [2-C-14]acetate, 14.6 mCi at 105 mCi/mmol was obtained in 8 steps including the formation of [1,3-C-14]acetone in the pyrolysis of barium [2-C-14]acetate. The key step was the formation of the dianion of [1,3-C-14]acetone oxime and its condensation with L-proline methyl ester.
