Reaction Steps

To a solution of 3-[3,5-bis(trifluoromethyl)phenylamino]-2-cyano-3-[3-(2-oxoazepan-1-yl)propylamino]acrylic acid tert-butyl ester (203 mg, 0.37 mmol) in DCM (6.0 mL) at 0° C. TFA (6.0 mL) was added. The resulting mixture was stirred at 0° C. for 30 min and then poured into an ice-cold, aqueous, saturated NaHCO3 -solution (100 mL). After dilution with DCM (30 mL) phases were separated, the aqueous layer was extracted (3×20 mL DCM), the combined extracts were washed with brine (2×50 mL), dried (magnesium sulfate) and concentrated, to yield 190 mg (100%) of the title compound as an oil (mixture of isomers). LCMS: elution at 9.97 min, MH+ : 449). 1H NMR (300 MHz, DMSO-d6): δ=1.45-1.80 (m, 8H), 2.40 (m, 2H), 2.95 (m, 1H), 3.21 (m, 2H), 3.35 (m, 6H), 3.58 (s, br, 1H), 7.35-7.70 (m, 3H).
