Reaction Steps

A solution of {1-methyl-3-[1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl]-1H-indol-5-yloxy}-acetic acid ethyl ester [120 mg, Reference Example 15(b)] in dry tetrahydrofuran (5 mL) was treated with lithium aluminium hydride (1.0M solution in tetrahydrofuran, 50 μl) at 0° C. under a nitrogen atmosphere. The mixture was allowed to warm to ambient temperature, then stirred for 3 hours and then carefully poured into water (75 mL). The mixture was extracted three times with ethyl acetate (25 mL). The combined organic extracts were washed with brine (75 mL), then dried over sodium sulfate and then evaporated to give the title compound (45 mg) as a colourless solid, m.p. 209–210° C. MS: 308 (MH+).
