Reaction Steps

(±)-tert-Butyl 4-(2-cyano-1-methoxy-1-oxopropan-2-yl)-5-methoxy-7-methyl-1H-indole-1-carboxylate (Example 155-D) (0.35 g, 0.940 mmol) was dissolved in EtOH (4.70 ml), cooled to 0° C. and added 10% KOH (2.64 ml, 4.70 mmol) and stirred for 1 hour. At this point, the reaction was placed in an ice bath and quenched with 1 N HCl (4.70 ml, 4.70 mmol). The reaction was diluted with water and ethyl acetate. The layers were separated and the ethyl acetate layer was removed, dried over Na2SO4 and concentrated to obtain the title compound which was used directly in the next reaction without purification. MS (ESI+) m/z 359.4 (M+H).
