Vorschrift

A solution of tert-butoxycarbonylamino-acetic acid 4-[2-amino-6-(5-chloro-2-ethoxy-phenyl)-pyrimidin-4-ylamino]-benzyl ester in ethyl acetate (15 ml) was treated with a solution of hydrogen chloride in dioxane (4.0 M, 15 ml). After stirring for 16 hours, the solid was filtered and dried under reduced pressure to provide the hydrochloride salt of the title compound (0.273 g, 48% yield). 1H NMR (DMSO-d6) δ 1.39 (t, 3H, J=6.4 Hz, CH3), 3.89 (d, 2H, J=4.9 Hz, CH2), 4.17 (q, 2H, J=6.2 Hz, CH2), 5.25 (s, 2H, CH2), 6.70 (s, 1H, Ar), 7.28 (d, 1H, J=8.7 Hz, Ar), 7.46 (d, 2H, J=8.4 Hz, Ar), 7.62-7.67 (m, 2H, Ar), 7.88 (d, 2H, J=7.4 Hz, Ar), 8.37 (s, 3H), 11.10 (s, 1H), 12.68 (s, 1H).
