Versuchsvorschrift

To a solution of ethyl 3-((3-((5-fluoro-2-((4-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)amino)phenyl)amino)-3-oxopropanoate (0.17 g) in THF (5 mL), in a 25 mL 3-necked RBF equipped with N2 bubbler, were added LiBr (0.182 g) and NaBH4 (0.081 g). The reaction mixture was stirred at reflux temperature for 3 hr. The reaction was monitored on TLC using ethyl acetate:hexane (8:2) as mobile phase. After completion, the reaction mixture was poured into water. The product was extracted with ethyl acetate and the organic layer was washed with brine and concentrated completely under reduce pressure at 40° C. The obtained solid was purified by column chromatography. Product was eluted with 100% ethyl acetate to give, after concentration, 10.2 mg of N-(3-((5-fluoro-2-((4-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)amino)phenyl)-3-hydroxypropanamide. 1H NMR: DMSO-d6 (400 MHz): 2.50 (s, 2H), 3.30 (s, 3H), 3.63 (t, 2H, J=4.4), 3.70 (t, 2H, J=5.2), 4.01 (t, 2H, J=4), 4.67 (t, 1H, J=5.2), 6.79 (m, 2H), 7.24 (t, 1H, J=8), 7.33 (d, 1H, J=7.6), 7.51 (m, 3H), 7.85 (s, 1H), 8.05 (d, 1H, J=3.6), 8.94 (s, 1H), 9.34 (s, 1H), 9.87 (s, 1H).
