Participants

Reaction Steps

To a solution of (R)-1-[4-(4-pyridin-2-ylmethyl-piperazin-1-yl)-pyrimidin-2-yl]-ethyl acetate (prepared according to the method of Example 182, Step A, 0.14 g, 0.33 mmol) in dioxane (6 mL) was added at ambient temperature 6 N aqueous potassium hydroxide (0.5 mL). After stirring for 3 h the solution was diluted with ethyl acetate and washed twice with water. The organic layer was separated, dried over magnesium sulfate, filtered, and the filtrate was concentrated to give the title compound as a white solid, 0.09 g (69%). 1H NMR (CDCl3, 300 MHz) δ 1.52 (d, 3H), 2.38-2.59 (m, 4H), 3.72-3.77 (m, 6H), 4.69 (q, 1H), 6.37 (d, 1H), 7.22 (d, 1H), 7.41 (d, 1H), 7.69 (m, 1H), 8.21 (d, 1H) 8.58, (d, 1H); mp: 68-70 IC; MS (CI) 300 (MH+); [a]D+16.2 (c 1.0, MeOH).
