実験手順

Methanol (0.70 mL) was added to a flask containing ethyl 4-butyrylbenzoate (82.8 mg, 0.376 mmol), 2-(4-(trifluoromethyl)phenyl)pyrimidin-5-amine (90.0 mg, 0.376 mmol) and decaborane (46.0 mg, 0.376 mmol) at room temperature under nitrogen. The resulting solution was stirred at room temperature overnight. The mixture was diluted with 1N HCl and extracted with ethyl acetate twice. The combined organic layers were dried over sodium sulfate, filtered and concentrated. Purification by column chromatography (0-35% ethyl acetate in heptane) gave ethyl 4-(1-(2-(4-(trifluoromethyl)phenyl)pyrimidin-5-ylamino)butyl)benzoate (40.0 mg, 24%). 1H NMR (400 MHz, CDCl3, δ): 8.32 (d, J=8.19 Hz, 2 H), 8.07 (s, 2 H), 7.98-8.04 (m, 2 H), 7.63 (d, J=8.19 Hz, 2 H), 7.36-7.41 (m, 2 H), 4.38-4.43 (m, 2 H), 4.35 (q, J=7.02 Hz, 2 H), 1.75-1.91 (m, 2 H), 1.36 (t, J=7.02 Hz, 3 H), 1.20-1.52 (m, 2 H), 0.94 (t, J=7.32 Hz, 2 H). MS (M+1): 444.3.
