Reaction Steps

To a solution of (R)-1-(4-chloro-pyrimidin-2-yl)-ethyl butyrate (prepared according to the method of Preparation Seven, 250 mg, 1.1 mmol) in dioxane (0.9 mL) was added concentrated hydrochloric acid (0.9 mL). This mixture was allowed to stir at room temperature for 5 h, quenched with saturated aqueous sodium bicarbonate followed by solid sodium bicarbonate until no more gas evolution was evident. Dichloromethane was added and the layers were separated. The aqueous phase was extracted with dichloromethane (3×) and the combined organic extracts were dried over sodium sulfate, filtered, and evaporated to give 125 mg (71%) of the title compound as a pale yellow oil. 1H NMR (CDCl3, 400 MHz) δ 8.59 (d, 1H), 7.25 (d, 1H), 4.92 (q, 1H), 3.81 (br s, 1H), 1.56 (d, 3H); MS (APCI) 159, 161 (MH+).
