Versuchsvorschrift

A suspension of 5% Pd/C (5.0 mg, 2.3×10−3 mmol), [4-(4-methyl-piperidin-1-yl)-3-nitro-phenyl]-methanol (i) (95 mg, 0.38 mmol), acetic acid (“HOAc”) (23 mg, 0.38 mmol), methanol (1 mL) and ethyl acetate (4 mL) was stirred in an atmosphere of hydrogen for 3 h. The reaction was filtered, concentrated in vacuo and the resulting [3-amino-4-(4-methyl-piperidin-1-yl)-phenyl]-methanol was used in the next step without further purification. A suspension of [3-amino-4-(4-methyl-piperidin-1-yl)-phenyl]-methanol, 5-cyano-2-furoyl chloride (64 mg, 0.44 mmol), PS morpholine (600 mg, 1.50 mmol), and DCM (10 mL) was stirred at room temperature for 30 min. The reaction was evaporated onto celite, and purified by column chromatography to give 5-cyano-furan-2-carboxylic acid [5-hydroxymethyl-2-(4-methyl-piperidin-1-yl)-phenyl]-amide. MS: 340 (M+1), 1H NMR (CDCl3, 300 MHz): δ 9.9 (s br, 1H), 8.4 (s, 1H), 7.3 (s, 1H), 7.25-7.1 (m, 3H), 4.7 (s, 2H), 3.0 (m, 2H), 2.8 (m, 2H), 1.9, (d, 2H), 1.8-1.4 (m, 3H), 1.1 (d, 3H).
