2-(2-(4-Chlorophenyl)oxazol-4-yl)-2-methyl-N-(3-(5-(trifluoromethyl)-1,2,4-oxadiazol-3-yl)benzyl)propan-1-amine was synthesized from 3-(5-(trifluoromethyl)-1,2,4-oxadiazol-3-yl)benzaldehyde and 2-(2-(4-chlorophenyl)oxazol-4-yl)-2-methylpropan-1-amine as described in example 7 step 3. The free amine was then treated with HCl in dioxane (2 M) at 0° C. and stirred at room temperature for 30 min. The reaction mixture was concentrated under reduced pressure. The crude was purified by washing with dry hexane to get 2-(2-(4-chlorophenyl)oxazol-4-yl)-2-methyl-N-(3-(5-(trifluoromethyl)-1,2,4-oxadiazol-3-yl)benzyl)propan-1-amine hydrochloride (20 mg, yield 6%). 1H NMR (400 MHz, DMSO-d6) δ 8.87 (br s, 2H), 8.26 (s, 1H), 8.11-8.08 (m, 2H), 7.85-7.80 (m, 3H), 7.69-7.65 (t, J=7.6 Hz, 1H), 7.55-7.52 (d, J=8.5 Hz, 2H), 4.28 (br s, 2H), 3.12 (m, 2H), 1.33 (s, 6H). MS (ESI) m/z: Calculated for C23H20ClF3N4O2: 476.12. found: 477.2 (M+H)+.
