, (2011/04/14)
The present invention provides 5,6-bicyclic heteroaryl-containing urea compounds of Formula I or II and use of the same for treating conditions mediated by protein kinase such as VEGFR2, c-Met, PDGFRβ c-Kit, CSFlR, or EphA2.

The synthesis of (-)-(R)-7-azatryptophan (2) from commercially available 7-azaindole (4) is described.The key step involved the diastereoselective alkylation of tert-butyl acetate (3) with 1-(tert-butyloxycarbonyl-3-(iodomethyl)-7-azaindole (14).The alkylation, conducted at -100 deg C in a THF/HMPA solvent using potassium hexamethyldisilazide as the base, afforded 7 in a greater than 98 percent diastereomeric excess.Hydrolysis and deprotecting gave (-)-(R)-7-azatryptophan.
