Lithium Bromide → HCID 68867386, compound

Participants

Reaction Steps

Compound 04-5 (4.74 g, 10.9 mmol) was converted with LiBr (1.1 g, 12.5 mmol, 1.1 equiv.), Li2CO3 (0.9 g, 12.5 mmol, 1.1 equiv.) to 04-6 using the procedure for 02-6. The crude product was filtered off after aqueous workup, washed with H2O and Et2O (25 mL) to give 04-6 (1.9 g, 5.7 mmol, 50%) as a grey solid. The mother liquor was evaporated and treated with Et2O to give a second crop of 04-6 (0.6 g, 1.9 mmol, 17%) as a brownish solid (total yield of 04-6: 2.6 g, 7.6 mmol, 67%).
