Participants

Reaction Steps

Compound 03-5 (4.54 g, 10.9 mmol) was converted with LiBr (1.04 g, 12 mmol, 1.1 equiv.), Li2CO3 (886 mg, 12 mmol, 1.1 equiv.) to 03-6 using the procedure for 01-6. The crude product was washed with EtOAc (15 mL) and washed with Et2O (2×15 mL) to give 03-6 (1.8 g, 5.4 mmol 49%) as a brownish solid. The mother liquor was evaporated and treated with Et2O to give a second crop of 03-6 (0.67 g, 2.0 mmol, 18%) as a brownish solid. Total yield of 03-6: 2.47 9, 7.4 mmol, 68%.
