実験手順

The product from Example 136C (240 mg, 0.5 mmol) and hydroxylamine hydrochloride (139 mg, 2.00 mmol) were dissolved into methanol (2 mL) and treated with Na2CO3 (318 mg, 3.0 mmol). The suspension was stirred at room temperature overnight and then heated at 70° C. three days. The mixture was cooled to room temperature and filtered, the solids being rinsed with 50% MeOH/CH2Cl2. The filtrate was concentrated, then partitioned between water and MeOH/CH2Cl2; some clean product remained undissolved and was separated. The organic phase was concentrated, dissolved in a little methanol, and seeded with the previously collected product. After this material had crystallized, both crops of product were rinsed with methanol and permitted to dry to provide the title compound as a white microcrystalline solid (49% yield). 1HNMR (300 MHz, CDCl3) δ 1.18 (d, 3H), 1.4-2.1 (m, 4H), 2.2-2.6 (m, 3H), 2.34 (s, 3H), 3.00-3.12 (m, 2H), 3.20-3.34 (m, 2H), 6.49 (s, 1H), 7.41-7.48 (m, 3H), 7.56-7.63 (m, 2H), 7.68 (dd, 1H), 7.70 (bs, 1H), 7.88 (dd, 1H).
