Product 1

HCID 86673733[Bis-(4-methoxy-phenyl)-phenyl-methyl]-{(R)-5,5-difluoro-4-[2-fluoro-5-(6-trifluoromethyl-pyridin-2-ylamino)-phenyl]-4,6,6-trimethyl-5,6-dihydro-4H-[1,3]oxazin-2-yl}-amineYield 81%

Procedure

In a manner analogous to that described in Example 3 a), the amination of [bis-(4-methoxy-phenyl)-phenyl-methyl]-[(R)-4-(5-bromo-2-fluoro-phenyl)-5,5-difluoro-4,6,6-trimethyl-5,6-dihydro-4H-[1,3]oxazin-2-yl]-amine (intermediate C4.1) with 6-(trifluoromethyl)pyridin-2-amine yielded the title compound (81% yield) as a pale yellow foam. MS (ISP): m/z=735.4 [M+H]+.
