Reaction Steps

In a 3 ml vial equipped with a small triangular magnetic stirring bar was placed 6-(5-amino-2-chlorophenyl)-2-(2-(dimethylamino)ethylamino)-8-methoxypyrido[2,3-d]pyrimidin -7(8H)-one (348 μmol). Triethylamine (344 μmol) was added, followed by aliquots of DMF stock solutions of HATU (320 μmol) and 4-chloro-3-(trifluoromethyl)benzoic acid (129 μmol), and the mixture was stirred at room temperature over night. The solution was transferred to maximum recovery HPLC vials and purified by prep. HPLC-MS. The collected fractions were transferred to centrifuge vials and lyophilized, giving 4-chloro-N-(4-chloro-3-(2-(2-(dimethylamino)ethylamino)-8-methoxy-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl) -3-(trifluoromethyl)benzamide as a solid (70%).
