実験手順

3-Cyclohexylamino-propionic acid ethyl ester (1.0 g, 5.0 mmol) and 4-chloro-2-methylsulfanyl-pyrimidine-5-carboxylic acid ethyl ester (1.17 g, 5.02 mmol) were combined in DCM (15 mL) and diisopropylethylamine (0.81 g, 6.3 mmol) was added. After 16 h, the solution was partitioned between water and DCM and the organic layer was dried (MgSO4) and concentrated. Chromatography (0-20% EtOAc/hexanes gradient) provided 1.63 g (84%) of the title compound. 1H-NMR (400 MHz, CDCl3) δ ppm 8.39 (s, 1H) 5.30 (s, 1H), 4.30 (q, 2H, J=7.1 Hz), 4.14 (q, 1H, J=7.1 Hz), 3.76-3.80 (m, 2H), 2.65-2.69 (m, 2H), 2.49 (s, 3H), 1.81-1.84 (m, 2H), 1.34-1.40 (m, 7H), 1.12-1.27 (m, 7H).
