Reaction Steps

LC/MS (m/z) [M+1]+618.8 (calculated for C29H29F3N4O6S, 618.63). 2-({5-[4-(4-Cyano-2-trifluoromethyl-phenoxy)-3-methoxy-benzylidene]-4-oxo-4,5-dihydro-thiazol-2-ylamino}-methyl)-morpholine-4-carboxylic acid tert-butyl ester (0.1 g, 0.16 mmol) was dissolved in dry dichloromethane (6 mL). To the reaction mixture was then added at 0° C. trifluoroacetic acid (2 mL). The reaction mixture was stirred at 0° C. for 1 hour and then at room temperature for 30 minutes. The reaction mixture was then partitioned with saturated aqueous sodium bicarbonate and dichloromethane. The organic layer was washed with brine, dried with Na2SO4, filtered and the solvent evaporated in vacuo to yield a crude oil. The crude oil was purified via flash chromatography (6% ammonia 2.0 M methanol/dichloromethane) to yield the compound as a solid (0.052 g, 63%).
