Procedure

To a solution of the product of Example 353E (16.1 mg, 0.036 mmol) in N,N-dimethylformamide (0.4 mL) was added triethylamine (0.011 mL, 0.079 mmol). The mixture was cooled to 0° C. and ethanesulfonyl chloride was added (0.0036 mL, 0.038 mmol). The mixture was warmed to 23° C. and stirred for 2 hours. The reaction mixture was concentrated under reduced pressure. The residue was purified by reverse phase chromatography, eluting with a gradient of 10% acetonitrile in 0.1% trifluoroacetic acid in water to 95% acetonitrile/0.1% trifluoracetic acid in water to give the title compound (7.7 mg, 40%). The sodium salt of the title compound was prepared by adding 1 N sodium hydroxide (0.029 mL, 0.0029 mmol) to a solution of the title compound (7.7 mg, 0.014 mmol) in water (0.4 mL) and stirring for thirty minutes. The reaction mixture was concentrated under reduced pressure. 1H NMR (300 MHz, DMSO-d6) δ 0.21 (bs, 2 H) 0.46 (d, 2 H) 0.99 (m, 1 H) 1.19 (t, 3 H) 3.01 (q, 2 H) 4.23 (s, 2 H) 5.85 (t, J=6.62 Hz, 1 H) 6.79 (s, 1 H) 6.93 (t, J=7.54 Hz, 1 H) 7.35 (t, J=6.99 Hz, 2 H) 7.59 (d, J=8.09 Hz, 1 H) 7.95 (d, J=6.62 Hz, 1 H).
