Example 51 General procedure for the synthesis of 4-(8-methoxy-5-(trifluoromethyl)quinazolin-2-ylamino)phenyl)(morpholino)methanone (Compound 500) PP028218.0002: Step 1. Prepare a mixture of 2-methoxy-5-(trifluoromethyl)aniline A. A methanolic solution of 4-methoxy-3-nitrobenzotrifluoride and 10% Pd/C catalyst (10% loading) was stirred overnight at room temperature in a hydrogen atmosphere. Upon completion of the reaction, the mixture was filtered through a diatomaceous earth pad to remove the catalyst, and the filtrate was concentrated under reduced pressure and dried under vacuum to afford the target product 2-methoxy-5-(trifluoromethyl)aniline A in 99% yield as an off-white solid.ESI-MS m/z: 192.1 (MH+).
