To a solution of (2E)-2,3-diphenylacrylic acid (0.32 g, 1.4 mmol) (prepared according to procedure given in example 1) in DMF (5 mL) was added Methyl-7-aminoheptanoate (0.25 g, 1.3 mmol), EDCI (0.55 g, 2.8 mmol) and HOBt (0.19 g, 1.4 mmol). TEA (0.6 mL, 4.3 mmol) was added dropwise with constant stirring to the above reaction mixture and it was stirred for 2 hours at room temperature. Reaction mixture was diluted with water (100 mL), extracted with ethyl acetate (2×100 mL). The organic layer was washed successively with water (3×50 mL), and brine solution (1×50 mL). The organic layer was dried over Na2SO4 and concentrated to afford the title compound (0.4 g, 61% yield).
