Reaction Steps
A solution of N-cyclopropyl-3-fluoro-5-(1H-indazol-5-yl)-4-methylbenzamide (example 60) (0.35 g) in dry DMF (5 ml) was treated with sodium hydride (60% oil dispersion, 0.08 g) at room temp under nitrogen then stirred for 20 min. A solution of methyl bromoacetate (0.2 ml) in dry DMF (0.5 ml) was added and stirring was continued for 1 h. Water (30 ml) was added and the mixture was extracted with ethyl acetate (×2). The organic extracts were washed with water (×3) and brine, dried (Na2SO4) and concentrated under vacuum. The residue was purified using a Varian Bond-Elut SPE cartridge (silica, 10 g) eluting with cyclohexane:ethyl acetate (4:1 to 1:1) to give the title compound as a yellow foam (0.26 g).
