tert-Butyl N-[4-[4-[(3S)-3-methylmorpholin-4-yl]-6-(methylsulfonylmethyl)pyrimidin-2-yl]phenyl]carbamate (1.09 g, 2.35 mmol) was dissolved in methanol (5 mL) and 4M hydrogenchloride in dioxane (5 mL) was added. The solution was stirred at room temperature overnight, then the mixture evaporated to a dark brown oil and dissolved in ethyl acetate (10 mL). Water (5 mL) was added followed by the addition of sodium bicarbonate solution until neutral pH was achieved (˜2 mL). The phases were separated and the organic phase washed with water (10 mL). The organic layer was dried over magnesium sulphate and evaporated to a pale yellow foam (805 mg).
