A 20-mL vial was charged with (3S)-3-methyl-4-(((2S)-4-(1,3-thiazol-2-ylsulfonyl)-2-piperazinyl)methyl)morpholine (210 mg, 0.61 mmol), 2-(4-bromophenyl)-1,1,1-trifluoropropan-2-ol (326 mg, 1.21 mmol, Example 27, Step 1), sodium tert-butoxide (175 mg, 1.82 mmol), Pd2(dba)3 (55.5 mg, 0.061 mmol), dicyclohexyl(2′,6′-diisopropoxybiphenyl-2-yl)phosphine (RuPhos) (42.4 mg, 0.091 mmol, Strem Chemicals, Newburyport, Mass.) and toluene (5 mL). the vial was sealed and heated to 100° C. for 3 h. The reaction was filtered, concentrated and purified via reverse-phase preparative HPLC using a Phenomenex Gemini C18 column (30×150 mm, 10 μm) eluting with 0.1% TFA in CH3CN/H2O (5% to 100% over 15 min) to give 1,1,1-trifluoro-2-(4-((2S)-2-(((3S)-3-methyl-4-morpholinyl)methyl)-4-(1,3-thiazol-2-ylsulfonyl)-1-piperazinyl)phenyl)-2-propanol (20 mg) that was a mixture of two isomers.
