Reaction Steps
A solution of the product of Example 205 (21.5 g, 0.05 mmol) in pyridine (1 mL) was treated with α-toluenesulfonyl chloride (38 mg, 0.2 mmol), heated in a microwave reactor at 120° C. for 120 minutes, cooled to 25C and concentrated under reduced pressure. The residue was triturated with water (1 ml), filtered, and washed with hexane:ethyl acetate (1:1). The crude product was chromatographed on silica gel, eluting with dichloromethane:methanol (399:1) to give the title compound (7 mg, 24%). 1H NMR (300 MHz, DMSO-d6) δ 0.99 (d, J=6.62 Hz, 6 H) 1.58 (m, 2 H) 1.69 (m, 1 H) 4.49 (m, 2 H) 4.59 (s, 2 H) 7.32 (m, 5 H) 7.51 (m, 2 H) 7.57 (d, J=2.21 Hz, 1 H) 7.71 (d, J=8.82 Hz, 1 H) 8.57 (dd, J=8.09, 1.84 Hz, 1 H) 8.90 (dd, J=4.78, 1.84 Hz, 1 H) 10.38 (s, 1 H) 14.08 (s, 1 H) 15.14 (s, 1 H) (ESI−) m/z 580 (M−H)−
