Reaction Steps

To a solution of {3-[(4-thiazol-2-yl-benzylamino)-methyl-]-phenoxy}-acetic acid tert butyl ester (111 mg, 0.270 mmol), prepared in Step A of Example 13i, triethylamine (120 mg, 1.19 mmol) and dichloroethane (10 mL) was added 5-pyridin-2-yl-thiophene-2-sulfonyl chloride (77.2 mg, 0.297 mmol). The reaction was stirred for 72 h and additional 5 pyridin-2-yl-thiophene-2-sulphonyl chloride (38.5 mg) was added. The reaction was stirred for an additional 48 h. The organic solution was washed sequentially with 5.5% HCl, water, saturated sodium bicarbonate solution, and brine. The organic solution was dried (MgSO4), filtered, and concentrated. Flash chromatography (CHCl3:MeOH 99:1) provided the title compound of Step A (58 mg). MS 633 (M+1).
