合成路线1
该中间体在本合成路线中的序号：(VIII)Deprotection of the 6-benzyloxypyrrolotriazine (I) by transfer hydrogenation with ammonium formate and Pd/C in DMF provides alcohol (II) , which is condensed with (R)-propylene oxide (III) in the presence of triethylamine , and optionally LiCl , in ethanol at 70 °C to give the hydroxypropyl derivative brivanib (IV) . Subsequent coupling of alcohol (IV) with N-Cbz-L-alanine (V) by means of HATU in the presence of DIEA and DMAP in DMF or THF gives the N-protected alanine ester (VI), which is finally deprotected by treatment with ammonium formate and Pd/C in DMF . Alcohol intermediate (II) is alternatively obtained by addition of methylmagnesium bromide to the 6-(ethoxycarbonyl)pyrrolotriazine derivative (VII) in THF to afford the tertiary alcohol (VIII), which undergoes oxidative cleavage to the key 6-hydroxypyrrolotriazine (II) in the presence of H2O2 and BF3·Et2O in dichloromethane .
