Procedure

A suspension of Compound 18a in a mixture of methanol and 1M NaOH solution was refluxed for 1 h. Additional water was added, and the resultant mixture was refluxed for another 1 h. The resultant clear solution was cooled to room temperature and 1M HCl solution was added under stirring. The resultant solid was filtered and washed with water and methanol and dried to provide Compound 18b. 1H NMR (DMSO-d6): δ 12.38 (s, 1H); 8.25 (d, J=7.8 Hz, 1H); 8.11 (s, 1H); 8.04 (d, J=8.1 Hz, 1H); 7.97 (d, J=8.1 Hz, 1H); 7.76 (d, J=3.6 Hz, 2H); 7.51 (m, 1H); 3.97 (s, 2H).
