Procedure
A mixture of the product of Step A (0.06 g; 0.126 mmol) and 10% KOH (0.1 ml) in dioxane (2 ml) was refluxed for 1 h and solvents were evaporated to dryness. The residue was treated with AcOH (0.5 ml) and evaporated to dryness in vacuo. The residue was purified by FCC (SiO2, CH2Cl2 saturated with concentrated NH4OH and MeOH, 85:15) to give the title compound (0.032 g; 55%), as a colourless solid. 1H-NMR (CD3OD+CDCl3) 8.37 (d, 1H, J=3 Hz); 8.09 (dd, 1H, J=3, 6 Hz); 7.77 (dd, 1H, J=3, 9 Hz); 7.68 (s, 1H); 7.6 (d, 1H, J=9 Hz); 7.02-7.07 (m, 2H); 4.38 (s, 2H); 4.05-4.21 (m, 8H); 1.44-1.49 9m, 6H).
