実験手順

A mixture of 4,6-dichloropyrimidine-5-carbonyl chloride (82.5 mg, 0.390), methyl 2-(4-(4-(2-(tert-butyldimethylsilyloxy)ethylamino)-3-fluorophenyl)cyclohexyl)acetate (110 mg, 0.26 mmol) and TEA (0.054 mL, 0.39 mmol) in THF (2 mL) was stirred at room temperature under nitrogen for 14 hours. The reaction mixture was concentrated to remove THF. The residue was diluted with EtOAc, washed with water, dried over MgSO4 and concentrated. The crude material was purified by a 12 g silica gel column eluted with 3-15% EtOAc in heptane to give methyl 2-(4-(4-(N-(2-(tert-butyldimethylsilyloxy) ethyl)-4,6-dichloropyrimidine-5-carboxamido)-3-fluorophenyl)cyclohexyl)acetate a colorless oil (60 mg). m/z=598.2 (M+1).
