Reaction Steps

Methyl 4-(3,4-dichlorobenzyl)-2-formylfuro[3,2-b]pyrrole-5-carboxylate (0.2 g) was dissolved in methanol (10 mL) and THF (10 mL) and cooled to 0° C. Sodium borohydride (26 mg) was added and the reaction stirred for 2 hours. The mixture was acidified with 2M HCl, partially evaporated, and extracted with ethyl acetate. Combined organic extracts were dried (MgSO4) and concentrated in vacuo to give a white solid (0.23 g), NMR d(CDCl3) 3.8 (3H, s), 4.65 (2H, d), 5.6 (2H, s), 6.2 (1H, s), 6.85 (1H, s), 7.0 (1H, dd), 7.2 (1H, d), 7.35 (1H, d); M/z (+) 340 (MH+), 332, 278.
