Reaction Steps

The compound 2-(5-chlorothiophen-2-yl)-1-(4-hydroxyphenyl)-1H-indole-3-carbonitrile (Example 86) was dissolved in DMSO (0.25 mL) and hydroxylamine (0.25 mL, 100 eq) was added from a 2M stock solution of hydroxylamine*hydrochloride neutralized with sodium hydroxide (pH=7.01 as measured with pH-meter). The mixture was stirred at 60° C. for 18 hours. The cooled mixture was diluted with brine and extracted with EtOAc and subjected to reversed phase preparative HPLC. Appropriate fractions were combined and evaporated, and identified by 1H-NMR and LC/MS. Purity was determined by analytical HPLC. ES/MS m/z: 386.3 (M+H), 384.2 (M−H); 1H NMR (acetone-d6, 500 MHz): 7.89 (m, 1H), 7.21-7.13 (m, 4H), 7.04 (m, 1H), 7.00-6.97 (m, 3H) and 6.91 (d, 1H, J=4.0 Hz).
