Reaction Steps

To a solution of 4-benzyl-4-hydroxypiperidine (0.95 g, 5.0 mmol) and triethylamine (0.51 g, 5.0 mmol) in dichloromethane (10 mL) was added (R)-1-(4-methanesulfonyloxy-pyrimidin-2-yl)-ethyl butyrate (prepared according to the method of Preparation Eight, 1.23 g, 4.0 mmol) and stirred at ambient temperature for 18 h. The mixture was washed once with water, once with saturated aqueous sodium chloride and the organic layer was dried over sodium sulfate and filtered. The filtrate was evaporated to an oil which was purified by flash chromatography (95:5 dichloromethane:methanol) to give the title compound of Example 174, Step A as a viscous oil, 0.99 g (52%). 1H NMR (CDCl3, 300 MHz) δ0.95 (t, 3H), 1.53 (d, 3H), 1.65-1.78 (m, 4H), 1.88 (m, 2H), 2.08 (m, 2H), 2.48 (t, 2H), 3.45 (m, 2H), 4.42 (br s, 1H), 5.68 (q, 1H), 6.41 (d, 1H), 7.30-7.48 (m, 5H), 8.18 (d, 1H); MS (CI) 384 (MH+).
