合成路线1
该中间体在本合成路线中的序号：(III)The reaction of 4-chloro-1-butanol (I) with allylamine (II) by means of K2CO3 in refluxing THF gives N-allyl-N-(4-hydroxybutyl)amine (III), which is condensed with the pyrrolo[2,3-d]pyrimidine derivative (IV) by heating at 130 C in DMSO to afford the tertiary amine (V). The reaction of (V) with TBAF and Ts-F in THF provides the 4-fluorobutyl derivative (VI). Finally, the hydrogenation of the allylic double bond of (VI) with H2 over Pd/C in ethanol gives the target LWH-154.

The reaction of (V) with TBAF and Ts-F in THF provides the 4-fluorobutyl derivative (VI). Finally, the hydrogenation of the allylic double bond of (VI) with 3H2 over Pd/C in ethanol gives the target tritium-labeled LWH-154.
