Participants

Reaction Steps

Two reactions were run simultaneously. For each reaction, a solution of Example 385H (0.26 g, 0.68 mmol) and lithium hydroxide hydrate (0.275 g, 6.5 mmol) in dioxane (3 mL) and water (1.5 mL) was heated to 160° C. for 15 minutes. The combined reaction mixture was acidified to pH 2.0 with 1 N HCl and extracted with ethyl acetate. The extract was dried (MgSO4), filtered, and concentrated to provide the desired product, 0.475 g, 94.8% yield. 1H NMR (DMSO-d6) δ 1.10 (t, 3H) 1.22 (t, 3H), 2.54 (q, 2H), 3.80 (q, 2H), 6.80 (d, 1H), 7.20 (d, 1H), 7.30 (t, 1H), 7.40 (dd, 1H), 7.65-7.75 (m, 2H), 9.90 (s, 1H), 13.25 (br s, 1H); MS (ESI(−)) m/e 366 (M−H)−.
