Reaktionsschritte

To a solution of (S)-ethyl 2-(2-(2-(1H-indazol-5-yl)pyridin-4-yl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (32 mg, 0.052 mmol) in DMF (1 mL), was added Cs2CO3 (34 mg, 0.104 mmol), iodoethane (5 μL, 0.062 mmol). The reaction was reacted at room temperature. After the reaction finished, the reaction mixture was washed by water, extracted by EtOAc, the organic phase was dried over MgSO4, filtered, concentrated down, purified by silica gel column, eluting by 0-100% EtOAc in hexanes to give (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-(1-ethyl-1H-indazol-5-yl)pyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate. LCMS-ESI+: calc'd for C36H35ClN4O3S: 639.2 (M+H+). found: 639.4;
