Reaction Steps

To a solution of Compound 3 (20 mg, 0.02 mmol) in a ice-bath was added 4M HCl in 1,4-dioxane (5 mL). After the addition, the reaction mixture was gradually increased to room temperature and stirred for 24 h. To this solution, ether (30 mL) was added and continuously stirred for 30 min. The resulting mixture was placed in the freezer for 2 h. Solid residue was quickly filtered, washed with ethyl ether (5 mL), immediately dissolved in H2O and CH3OH, and lypophilized to provide pure Compound 4 as a light brownish solid (19 mg, 97%). 1H NMR (CD3OD) 0.71 (s, 3H), 0.58-0.95 (m, 6H), 0.96-1.17 (m, 5H), 1.21-2.05 (m, 26H), 2.10-2.52 (m, 5H), 2.55-3.09 (m, 4H), 3.15-4.12 (m, 10H), 7.27 (d, 2H), 7.56 (d, 2H). HRMS (Positive ion FAB) Calcd for C45H72N5O10 [M+H]+ m/z 842.5279. Found: [M+H]+ m/z 842.5265.
