A mixture of the ester from Step 4 (2.77 g), 90% formic acid (70 ml) and mercuric acetate (7.17 g) was stirred under an argon atmosphere at ambient temperature for 3 hours. The reaction mixture was poured into a mixture of water (350 ml) and CH2Cl2 (700 ml) and H2S gas was passed through the vigorously stirred mixture for 5 minutes. The organic phase was separated, filtered through celite, washed with water, dried (MgSO4) and reduced to dryness to provide the title compound, m.p. 103°-105°.
