Versuchsvorschrift

Methyl hydrogen isophthalate (1.5 g, 8.2 mmol), 2-amino-4-(benzyloxy)butan-1-ol hydrochloride (2 g, 8.6 mmol), diisopropylethylamine (4.2 mL, 24.7 mmol), and HATU (3.8 mg, 9.9 mmol), in DMF (15 mL) are stirred at room temperature 1 h. The reaction is diluted in ethyl acetate and washed with water, 1N hydrochloric acid (aq), saturated sodium bicarbonate, brine, dried (magnesium sulfate), filtered, and concentrated under reduced pressure. Purification by flash column chromatography (silica gel, 4% methanol/chloroform) provides the title compound. 1H NMR (400 MHz, CDCl3) δ 8.44 (s, 1H), 8.18 (d, 1H, J=7.9 Hz), 7.86 (d, 1H, J=7.9 Hz), 7.43 (t, 1H, J=7.6 Hz), 7.42-7.35 (m, 5H), 4.59 (s, 2H), 4.33 (m, 1H), 3.96 (s, 3H), 3.88-3.72 (m, 4H), 3.53 (s, 1H), 2.08 (m, 2H).
