Reaction Steps

N-{(1R,2R)-1-[(2-Acetoxyacetyl)amino]-2,3-dihydro-1H-inden-2-yl}-2-chloro-6H-thieno[2,3-b]pyrrole-5-carboxamide (Example 39; 393 mg, 0.92 mmol) was dissolved in THF (5 mL), MeOH (5 mL) and K2CO3 (50 mg) were then added and the suspension stirred at ambient temperature for 4 hours. Water (10 mL) was added and the aqueous phase was extracted with EtOAc (3×10 mL). The combined organic phases were washed with water (50 mL), brine (50 mL) and dried (MgSO4). The solvent was removed by evaporation under reduced pressure, the crude product was triturated (EtOAc:isohexane, 1:5), filtered, washed with isohexane (5 mL) and dried to give the title compound (257 mg, 72%) as a white solid.
