2-Iodo-1,3-oxazole → 4-[(2-{[4-(1,3-Oxazol-2-yl)phenyl]oxy}ethyl)(2,2,2-trifluoroethyl)amino]-2-(trifluoromethyl)benzonitrile

Participants

Reaction Steps

Synthesized as described in Example 40B from 4-[(2-{[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]oxy}ethyl)(2,2,2-trifluoroethyl)amino]-2-(trifluoromethyl)benzonitrile (Example 40A) and 2-iodo-1,3-oxazole (step A above), with the following exceptions: additional 2-iodo-1,3-oxazole (0.3 equiv) was added after 2 h of heating, additional Pd(PPh3)4 (0.005 g) was added after 4 h of heating, and heating was maintained for only 6 h: MS (ESI) m/z 456 (M+1).
