실험 절차

To a solution of 6-chloro-spiro[chroman-2,4′-piperidin]-4-one hydrochloride (prepared according to the method of Example 78, Step A, 175 mg, 0.61 mmol) in isopropanol (5 mL) was added (R)-1-(4-chloro-pyrimidin-2-yl)-ethyl butyrate (prepared according to the method of Preparation Seven, 160 mg, 0.70 mmol) followed by triethylamine (0.29 mL, 2.1 mmol). This mixture was stirred at reflux for 1.5 h, concentrated, and purified by flash column chromatography (1% methanol/chloroform) to give 270 mg (100%) of the title compound of Example 78, Step B as a yellow oil. 1H NMR (CDCl3, 400 MHz) δ 8.19 (d, 1H), 7.83 (d, 1H), 7.44 (dd, 1H), 6.97 (d, 1H), 6.37 (d, 1H), 5.64 (q, 1H), 4.18 (app s, 2H), 3.34 (t, 2H), 2.72 (s, 2H), 2.37 (t, 2H), 2.10 (d, 2H), 1.71-1.60 (c, 4H), 1.55 (d, 3H), 0.94 (t, 3H); MS (APCI) 444, 446 (MH+).
