Reaction Steps

150 mg of 2-(3,4-Diethoxy-benzoylamino)-2-methyl-propionic acid and 130 mg of 5-Benzyl-4-phenyl-thiazol-2-ylamine (WO2006082952) were stirred in 2 ml of acetonitrile at room temperature. 120 mg of EDCl and 100 mg of HOBT were added and the reaction mixture was stirred at 50° C. for 2 days and cooled to room temperature. It was diluted with water and the resulting precipitates were collected by filtration followed by washing with water. The filter cake was then purified by column chromatography (heptane/ethyl acetate=3/1) to provide the title compound. 1H NMR (400 MHz. CD3OD) δ 1.34-1.54 (m, 3H) 1.44 (d, J=5.31 Hz, 3H) 1.65 (s, 7H) 4.14 (qd, J=6.95, 2.53 Hz, 4H) 4.23 (s, 2H) 7.01 (d, J=8.46 Hz, 1H) 7.16-7.26 (m, 3H) 7.26-7.45 (m, 6H) 7.47-7.67 (m, 4H). m/z 545.1 (MH+).
