To a solution of the product of Example 353E (16.7 mg, 0.037 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 1-propane sulfonyl chloride was added (0.005 mL, 0.041 mmol). The mixture was warmed to 23° C. and stirred for 1.5 hours. The reaction mixture was concentrated under reduced pressure. The residue was purified by reverse phase chromatography, eluting with a gradient of 10% acetonitrile/0.1% trifluoroacetic acid in water to 95% acetonitrile/0.1% trifluoracetic acid in water to give the title compound (9.9 mg, 48%). 1H NMR (300 MHz, DMSO-d6) δ 0.15 (d, J=4.04 Hz, 2 H) 0.42 (d, J=7.35 Hz, 2 H) 0.99 (m, 4 H) 1.69 (m, 2 H) 2.84 (d, J=7.35 Hz, 2 H) 3.06 (m, 2 H) 4.27 (d, J=6.25 Hz, 2 H) 6.35 (bs, 1 H) 7.37 (s, 1 H) 7.42 (t, J=7.54 Hz, 2 H) 7.75 (t, J=6.07 Hz, 1 H) 7.87 (t, J=7.17 Hz, 1 H) 8.07 (d, J=8.46 Hz, 1 H) 8.15 (dd, 1 H) 14.52 (bs, 1 H).
