Reaction Steps

A solution of Example 34B (0.053 g, 0.112 mmol), mesyl chloride (0.035 mL, 0.447 mmol), and pyridine (0.073 mL, 0.893 mmol) in acetone (1.5 mL) was stirred at 25° C. for 18 hours. The solution was partitioned between ethyl acetate and dilute citric acid and the layers were separated. The ethyl acetate layer was dried with sodium sulfate, filtered, and concentrated in vacuo. The residue was chromatographed on silica gel eluting with methylene chloride and 2.5% methanol in methylene chloride to give the desired product (0.049 g, 84%). 1HNMR (300 MHz, DMSO-d6): δ ppm 0.43 (m, 1 H) 0.74 (m, 7 H) 1.34 (m, 1 H) 1.57 (m, 3 H) 2.15 (m, 2 H) 3.08 (m, 3 H) 7.56 (m, 3 H) 7.75 (m, 3 H) 8.16 (m, 1 H) 10.26 (m, 1 H) 13.76 (m, 1 H).
