Participants

Reaction Steps

A solution of Example 48F (1.91 g, 3.45 mmol) in 4 M hydrochloric acid in 1,4-dioxane (30 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 1.58 g (93%) of a yellow solid. 1H NMR (300 MHz, DMSO-d6): δ ppm 0.38 (td, J=12.87, 3.68 Hz, 1 H) 0.78 m, 10 H) 1.59 (s, 3 H) 2.08 m, 1 H) 2.23 (td, J=12.78, 4.60 Hz, 1 H) 7.07 m, 2 H) 7.53 m, 2 H) 7.77 (m, 2 H) 8.16 (d, J=7.72 Hz, 1 H) 13.58 (s, 1 H); MS (ESI+) m/z 454 (M+H)+.
