Stir a mixture of (S)-(2,4-dichlorobenzyl)-pyrrolidin-3-ylamine (313 mg, 1.28 mmol), 2-chloro-5-bromopyrimidine (248 mg, 1.28 mmol) and diisopropylethylamine (335 μL, 1.91 mmol) in acetonitrile (2 mL) at 80° C. overnight. Concentrate and chromatograph on SCX-2 column to give the title compound (450 mg, 87%). Form the hydrochloride by essentially the procedure in Example 1 to give 1H NMR (400 MHz, MeOH-d4) δ 8.41 (2H, s), 7.62-7.67 (2H, m), 7.49 (1H, dd, J=8.31, 1.96 Hz), 4.46 (2H, d, J=5.62 Hz), 4.16 (1H, m), 3.99-4.05 (1H, m), 3.79-3.86 (2H, m), 3.65 (1H, m), 2.60 (1H, m), 2.28-2.37 (1H, m), MS (ES): m/z=402 [M+].
