실험 절차

As shown in step 4-v of Scheme 4, a mixture of 4,6-dichloropyrimidine (817 mg, 5.49 mmol), 2-(2-methoxyphenyl)-1-propanamine (0.997 g, 6.03 mmol), and DIEA (2.13 g, 2.87 mL, 16.5 mmol) in isopropanol (5.0 mL) was stirred for 18 hours. The reaction mixture was concentrated under reduced pressure and the residue purified by medium pressure chromatography on silica gel (25% EtOAc in hexanes) to give 6-chloro-N-(2-(2-methoxyphenyl)propyl)pyrimidin-4-amine as a colorless solid (Compound 2012, 1.18 g, 77% yield): 1H NMR (CDCl3) δ 8.31 (s, 1H), 7.23 (dd, J=12.0, 4.5 Hz, 2H), 7.03-6.87 (m, 2H), 6.41 (s, 1H), 5.42 (s, 1H), 3.89 (s, 3H), 3.67-3.18 (m, 3H), 1.35 (d, J=6.8 Hz, 3H).
