Versuchsvorschrift
The product from Example 144B (1.00 g, 3.62 mmol) was added slowly to 4 M hydrochloric acid (10 mL, 40 mmol) and stirred at room temperature. After stirring overnight, ether was added and the solid filtered. Dried in vacuum oven to a white solid (0.817 g; 84%). 1H NMR (400 MHz, methanol-d4) δ 1.77 (s, 6H), 3.65 (s, 4H), 7.41 (d, J=9.8 Hz, 1H), 7.70 (d, J=2.6 Hz, 1H), 7.79 (dd, J=2.7, 9.8 Hz, 1H).
