実験手順

A solution of Example 39G (0.713 g, 1.32 mmol) in 4M hydrochloric acid in 1,4-dioxane (10 mL) was stirred at 25° C. for 1 hour. The solution was concentrated in vacuo and the residue was triturated in diethyl ether to give the title compound (0.537 g, 85%). 1H NMR (300 MHz, DMSO-d6): δ ppm 0.42 (m, 1 H) 0.74 (m, 7 H) 1.32 (m, 1 H) 1.58 (m, 3 H) 2.15 (m, 2 H) 7.07 (m, 2 H) 7.51 (m, 2 H) 7.77 (m, 2 H) 8.16 (m, 1 H) 13.57 (m, 1 H). MS (ESI−) m/z 438 (M−H)−.
