Yield:91347-99-8 88 %

Reaction Conditions:

with trifluoroacetic acid in dichloromethane at 20;Inert atmosphere;

Steps:

9.2 Step 2: 4-(4-bromophenyl) - 1, 2, 3, 6-tetrahydropyridine

Trifluoroacetic acid (1.250 ml, 16.32 mmol)was added to solution of tert-butyl4-(4-bromophenyl)-3,6-dihydropyridine-1(2H)-carboxylate (1.38 g, 4.08 mmol) in CH2CI2 (10ml) under argon at RT. The reaction mixture was stirred at RT for 1 h. Complete conversion to the desired product was observed by LCMS. The mixture was concentrated and the residue was dissolved in MeOH (20 mL), passed through a 5 G porapak cation exchange cartridge and the eluant was removed to afford the product as a beige solid (854 mg, 88%). LCMS: [M + H]+ = 240.36.
