Reaction Conditions

Reaction Steps

To a stirred solution of compound (19) (107 mg, 0.15 mmol) in DMF (0.50 mL) was added tetrabutylammonium fluoride (190 μL of a 1.0 M solution in THF, 0.19 mmol). After 10 min, the reaction mixture was diluted with water (3.0 mL) and cooled to 0° C. for 30 min. The resulting solid was collected by filtration and purified by flash column chromatography, eluting with 4.5% methanol in DCM, to afford the title compound, Example 1, (70 mg, 85%) as a white solid: m/z 534/536 (M+H)+ (ES+); Rt 3.73 min; 1H NMR (500 MHz, DMSO-d6) δ: 4.42 (1H, s), 5.30 (2H, s), 5.77 (2H, s), 6.16 (1H, d), 6.79 (1H, t), 6.84 (1H, dd), 6.89-6.96 (2H, m), 7.04 (1H, t), 7.14 (1H, d), 7.30 (1H, t), 7.70 (1H, d), 7.75 (1H, d), 7.80-7.87 (1H, m), 8.18 (1H, s), 9.67 (1H, s).
