Reaction Steps

Using an analogous reaction procedure and workup as described in Example 1, step 1, benzo[b]thiophene-2-carbaldehyde (2.1 g, 0.012 mol) in ethanol (100 mL) was reacted with nitro methane (0.7 mL, 0.012 mol) and 10N NaOH (0.51 g, 0.012 mol). The resulting mixture was stirred at 0° C. for 1 hr to afford 2.1 g of the product (84% yield).
