该中间体在本合成路线中的序号：(IV)The synthesis of [2H]-, [3H]- and [14C]-radiolabeled sorbinil has been described: [2H]- and [3H]-sorbinil are prepared by chlorination of sorbinil (I) with Cl2 and FeCl2 in dry DMF to give the 8-chloro derivative (II), which is then reduced with deuterium or tritium over Pd/C in ethanol. [14C]-Labeled sorbinil is prepared by cyclization of 6-fluoro-3,4-dihydro-2H-benzo[b]pyran-4-one (III) with [14C]-potassium cyanide and ammonium carbonate in hot ethanol-water to give radiolabeled racemic sorbinil, which is then submitted to optical resolution with brucine in ethanol.
