Procedure

To a solution of [5-(3-amino-ethoxy)-1,3-dihydro-isoindol-2-yl]-(2,4-dihydroxy-5-isopropyl-phenyl)-methanone hydrochloride (100 mg, 0.255 mmoles) in DMF (10 ml) was added EDC (59 mg, 0.306 mmoles), HOBt (41 mg, 0.306 mmoles), morpholin-4-yl-acetic acid (37 mg, 0.255 mmoles) and triethylamine (43 μl, 0.306 mmoles) and stirred at ambient temperature for one hour. To the reaction mixture was added further EDC (20 mg, 0.104 mmoles), HOBt (14 mg, 0.104 mmoles), morpholin-4-yl-acetic acid (12 mg, 0.083 mmoles) and triethylamine (14 μl, 0.100 mmoles) and stirred at ambient temperature for a further 2 hours. Solvent removed in vacuo. The residue was purified by flash chromatography [Biotage SP4: 25S, flow rate 25 ml/min, gradient 20% DMAW 90 in DCM to 100% DMAW 90] and then by preparative HPLC to give N-{2-[2,4-dihydroxy-5-isopropyl-benzoyl)-2,3-dihydro-1H-isoindol-5-yloxy]-ethyl}-2-morpholin-4-yl-acetamide as a colourless viscous oil (40 mg, 33%). 1H NMR (Me-d3-OD) 7.20 (1H, br s); 7.18 (1H, s); 6.90 (2H, br m); 6.40 (1H, s); 4.10 (2H, t); 3.73 (4H, m); 3.63 (2H, t); 3.20 (1H, m); 3.18 (2H, s); 2.60 (4H, m); 1.25 (6H, d). MS: [M+H]+ 484.
