The reaction mixture was concentrated then transferred to a vial charged with Cl2Pd(AmPhos) (Sigma- Aldrich, St. Louis, MO, 0.291 g, 0.412 mmol), tert-butyl 5-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)-3,4-dihydroisoquinoline-2(lH)- carboxylate (ASW Medchem, Brunswick, NJ, 2.96 g, 8.23 mmol), and potassium phosphate (8.74 g, 41.2 mmol). 8 mL dioxane and 4 mL water were added, and the reaction mixture was heated to 120 C for 2 hours. After cooling to rt, the reaction mixture was poured into water and extracted with DCM. The organics were concentrated then purified by reverse phase column chromatography [RediSep Gold CI 8 150g, 15 to 100% (0.1% NH4OH in MeOH)/(0.1% NH4OH in water)] yielding tert-butyl 5-(2-(4-methylpiperazin-l-yl)-4- (trifluoromethyl)phenyl)-3,4-dihydroisoquinoline-2(lH)-carboxylate (1.68g, 3.53 mmol).

The reaction mixture was diluted with diethyl ether, washed with water, the organics dried over MgS04 and concentrated to provide tert- butyl 5-(2-fluoro-4-(trifluoromethyl)phenyl)-3,4-dihydroisoquinoline-2(lH)- carboxylate. The resulting residue was dissolved in 10 mL THF and was treated with HCI 4 N in dioxane (9.74 ml, 39.0 mmol), and allowed to stir at room temperature overnight. The reaction mixture was diluted with diethyl ether/heptane, and the resulting solid was filtered and dried yielding 5-(2-fluoro-4-(trifluoromethyl)phenyl)- 1,2,3,4-tetrahydroisoquinoline hydrochloride (1.930 g, 5.82 mmol).

YieldReaction ConditionsOperation in experiment
1.6 g tert-Butyllithium (21.8 mL, 1.7M in pentane, 37.0 mmol) was added dropwise to 4-bromo-3-fluorobenzotrifluoride (5.00 g, 20.58 mmol) in THF (50 mL) at ?70° C. After 1 h, 3-oxotetrahydrofuran (1.78 g, 20.58 mmol) in THF was added dropwise. The reaction mixture was warmed to ?10° C. mixture and quenched with NH4Cl satured solution. Ethyl acetate was added, the organic layer was separated, dried over sodium sulfate and evaporated. The crude obtained was purified by flash chromatography (eluent: cyclohexane/AcOEt; gradient from 0percent to 80percent of AcOEt) to obtain 1.6 g of the 3-(2-fluoro-4-trifluoromethyl-phenyl)-tetrahydro-furan-ol.GC-MS (Method 9): Rt=7.58 minGC-MS (Method 9): Rt=7.58 min
