Product 1

HCID 86732245(4S,6S)-4-(5-((3-chloro-1,7-naphthyridin-8-yl)amino)-2,3-difluorophenyl)-4-methyl-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-2-amine

Procedure

The titled compound was synthesized by procedure and steps analogous to those described in Method B, Step 2, Example 8 above, but using (4S,6S)-4-(5-amino-2,3-difluorophenyl)-4-methyl-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-2-amine (17i, Example 163, Method Y step 9) in step 2 and 3,8-dichloro-1,7-naphthyridine (intermediate 2). MS m/z=472.1 [M+H]+. Calculated for C20H15ClF5N50: 471.8
