Reaction Steps

To a round bottom flask containing 2-[8-(benzyloxy)-5-chloroquinolin-7-yl]-1-{5-[(dimethylamino)methyl]-2-furyl}ethanamine (0.710 mmol) at 0° C. was added a solution of isobutyryl chloride (0.852 mmol, 1.2 eq.) and triethylamine (0.852 mmol, 1.2 eq.) in tetrahydrofuran (5 mL) that was pre-mixed and stirred 5 min prior to addition. After warming to room temperature, the resulting solution was stirred 2 h and quenched with saturated aqueous sodium bicarbonate solution (1 mL) and stirred 5 min. The reaction was diluted with 0.1N NaOH (15 mL) and extracted with ethyl acetate (3×10 mL). The combined organic layers were dried (MgSO4), filtered and concentrated to a yellow syrup that was purified by column chromatography to afford the final product as a white solid (0.344 mmol, 47% for 2 steps). HRMS: calcd for C29H32ClN3O3+H+, 506.22049; found (ESI, [M+H]+ Obs'd), 506.2208.
