Reaction Steps
A solution of benzaldehyde (0.0056 mL, 0.056 mmol) and 2-(4-chlorophenyl)propane-1,3-diamine (10.8 mg, 0.059 mmol) in 0.7 mL t-BuOH was heated at 70° C. for 15 min. The reaction mixture was cooled to rt and treated with K2CO3 (38.5 mg, 0.279 mmol) and iodine (17.7 mg, 0.070 mmol). The reaction mixture was stirred for 5 min at rt and then heated to 70° C. for 2.5 hours. The reaction mixture was cooled to rt and saturated aqueous Na2SO3 was added drop-wise until the color changed from orange to yellow. The reaction mixture was partitioned between EtOAc and aqueous Na2CO3 solution, the EtOAc layer washed with H2O, brine, dried with anhydrous Na2SO4 and concentrated. The residue was chromatographed using basic aluminum oxide column and eluting with 5% MeOH/CHCl3 to give the title compound as an off-white solid (13.1 mg, 87%). 1H NMR (CDCl3) δ: 7.67-7.70 (m, 2H), 7.36-7.43 (m, 3H), 7.30-7.32 (m, 2H), 7.14-7.18 (m, 2H), 3.70 (dd, J=12.9, 4.4 Hz, 2H), 3.50 (dd, J=13.5, 10.3 Hz, 2H), 3.00 (tt, J=10.0, 4.8 Hz, 1H).
