“…Recrystallization from methanol afforded the triamide derivative based on 1 H NMR analysis (0.266 g, 79%). 1 (4R,9R,17R,22R)-27-bromo-29-methoxy-9,17-diphenyl-3, 10,13,16,23-pentaoxatetracyclo[23.3.1.0 4,9 .0 17,22 ]nonacosa-1 (28), 25(29), 26-triene (22) A solution of diol (R,R,R,R)-21, which was prepared according to the literature [34], (638 mg, 1.40 mmol) and 4-bromo-2,6-bis(bromomethyl)-1-methoxybenzene (523 mg, 1.40 mmol) in dry THF (160 ml) was added dropwise to a boiling mixture of sodium hydride (225 mg, 5.61 mmol) and dry THF (70 ml). The mixture was refluxed for an additional 14 h under dry nitrogen.…”
