Participants

Reaction Steps

A solution of methyl 4-[[hexahydro-4-[2-[4-(phenylmethyl)phenoxy]ethyl]-1H-1,4-diazepin-1-yl]methyl]benzoate (55 mg, 0.12 mmol) in methanol (4 mL) was stirred as a solution of aqueous sodium hydroxide (0.60 mL, 2 M) was added. The reaction was stirred for 17 hours at ambient temperature. The reaction was concentrated under reduced pressure. The residue was diluted with water, adjusted to pH 8 with 1 M aqueous hydrochloric acid, and extracted with butanol. The combined organic layers were concentrated under reduced pressure. Flash chromatography gave 46 mg of 4-[[hexahydro-4-[2-[4-(phenylmethyl)phenoxy]ethyl]-1H-1,4-diazepin-1-yl]methyl]benzoic acid; 1H NMR (300 MHz, CD3OD) δ 7.94 (d, 2H), 7.36 (d, 2H), 7.21 (dd, 2H), 7.13 (d, 2H), 7.12 (dd, 1H), 7.07 (d, 2H), 6.82 (d, 2H), 4.08 (t, 2H), 3.82 (s, 2H), 3.75 (s, 2H), 3.05 (t, 2H), 2.99 (m, 4H), 2.81 (m, 2H), 2.80 (m, 2H), 1.88 (m, 2H) ppm.
