Example 41D (2R)-ethyl 2-((5-((1S)-3-chloro-4-formyl-2-methylphenyl)-6-(4-fluorophenyl)thieno[2,3-d]pyrimidin-4-yl)oxy)-3-(5-(((2-(4-cyclopropylpiperazin-1-yl)ethyl)amino)methyl)-2-((2-(2-methoxyphenyl)pyrimidin-4-yl)methoxy)phenyl)propanoate To a mixture of Example 41C (53 mg) in dichloromethane (2 mL) was added 1-cyclopropylpiperazine (24 mg). The mixture was stirred for 20 minutes at room temperature before the addition of sodium triacetoxyborohydride (33 mg). The mixture was stirred at room temperature for 40 minutes. The reaction mixture was diluted with ethyl acetate (200 mL), washed with water and brine, and dried over sodium sulfate. Filtration and evaporation of the solvent provided the title compound, which was used in the next reaction without further purification. MS (ESI) m/z 1027.4 (M+H)+.
