Reaction Steps

A solution of 114 (1.9 g) in DMF (100 mL) was treated with SnCl2-2H2O (4 g). After 4 h, additional SnCl22H2O (1 g) was added three times over three days. The solvent was then evaporated, the residue suspended in H2O-EtOAc, the mixture neutralized with 5N NaOH, and the mixture filtered. The. organics were separated, washed with brine, dried, and the solvent evaporated to give a brown foam (1.9 g).
