Versuchsvorschrift

The solution of Example 5F (200 mg. 0.66 mmole), pyridine (300 mg) and methanesulfonyl chloride (227 mg., 2.00 mmole) in chloroform (3 mL) was stirred for 1 hour, washed with aqueous HCl (1M), dried (Na2SO4), filtered and concentrated under reduced pressure. Toluene was added and then concentrated. Heptane was added and concentrated under reduces pressure to provide the titled compound (199 mg. 80%). 1H NMR (300 MHz, CDCl3) δ 2.95 (s, 3H), 3.94 (s, 3H), 6.00 (s, 1H), 6.30 (s, 1H), 6.61 (d, J=2 Hz, 1H), 6.62 (dd, J=10 Hz, 2 Hz, 1H), 6.69 (dd, J=9 Hz, 1 Hz, 1H), 7.15 (t, J=9 Hz, 1H), 7.25 (dd, J=9 Hz, 2 Hz, 1H), 7.32-7.39 (m, 5H), 8.45 (d, J=9 Hz, 1H); MS (APCI) m/e 382 (M+H), 399 (M+NH4).
