Reaction Steps

To (5-Bromo-pyridin-2-yl)-(4-chloro-benzyl)-amine (41, 10.00 g, 0.03360 mol) in tetrahydrofuran (400.0 mL) under an atmosphere of nitrogen at −78° C. was added n-butyllithium (17.5 mL, 2.00M in cyclohexane). After 90 minutes, tert-butyllithium (42.00 mL, 1.70M in hexane) was added to the reaction. After 80 minutes, N,N-dimethylformamide (6.9 mL, 0.089 mol) was added to the reaction. The reaction mixture was stirred at −78° C. for 2 hours, then allowed to warm to room temperature for 1 hour. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated to give the crude compound, which was crystallized from tert-butoxyl methyl ether to provide compound (42, 7.66 g, 92.2%).
