Procedure

A mixture of Example 39H (23.8 mg, 0.050 mmol), pyridine (31.6 mg, 0.40 mmol) and 6-acetylamino-2-naphthalenesulfonyl chloride (56.7 mg, 0.20 mmol, prepared by the procedure as described in J. Med. Chem., 1995, 38, 8, p. 1344-1354) in acetone (1.5 mL) was stirred at rt for 18 h. The reaction mixture was evaporated in vacuo and partitioned between ethyl acetate and 1 N HCl. The organic phase was separated, dried (MgSO4), filtered, and evaporated in vacuo. The residue was purified by chromatography on silica gel eluting with 99:1 dichloromethane/methanol to provide the title compound (20.8 mg, 61% yield). 1H NMR (300 MHz, DMSO-d6) δ 0.38 (m, 1H) 0.66 (d, J=7.35 Hz, 3H) 0.68 (d, J=6.99 Hz, 3H) 0.80 (m, 1H) 1.30 (m, 1H) 1.53 (s, 3H) 2.02 (m, 1H) 2.10 (s, 3H) 2.18 (m, 1H) 7.52 (m, 4H) 7.69 (m, 4H) 7.99 (d, J=8.82 Hz, 1H) 8.07 (d, J=8.82 Hz, 1H) 8.11 (d, J=8.09 Hz, 1H) 8.38 (s, 2H) 10.32 (s, 1H) 10.87 (s, 1H) 13.72 (s, 1H).
