Procedure

A solution of Example 17E (13 mg) was dissolved in acetonitrile (1 mL) and treated with sodium hydroxide solution (1.0 N, 24.3 μL, 0.0243 mmol). After stirring for 30 min, the solution was frozen and lyophilized to afford the title compound as a fluffy grey solid (12.8 mg, 55% overall). 1H NMR (300 MHz, DMSO-d6): δ 0.65 (m, 8 H) 0.86 (d, J=2.94 Hz, 2 H) 1.65 (d, J=3.68 Hz, 2 H) 2.05 (m, 2 H) 7.43 (m, 6 H) 9.58 (s, 1 H) 15.21 (s, 1 H).
