Procedure

To a stirred mixture of methyl 1-(tosyloxy)-3,6,9,12,15,18,21,24,27,30,33,36-dodecaoxanonatriacontan-39-oate (265b)(700 mg, 0.890 mmol) and (5-amino-1,3-phenylene)dimethanol (26) (150 mg, 0.978 mmol) in anhydrous DMF (2.0 ml) was added potassium carbonate (184 mg, 1.334 mmol). The reaction was stirred at 80° C. overnight. The mixture was cooled to room temperature, quenched with water and extracted with 10% Methanol/Methylene chloride. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The crude product was purified by silica gel chromatography (eluted with 5→15% MeOH/CH2Cl2) to give methyl 1-(3,5-bis(hydroxymethyl) phenylamino)-3,6,9,12,15,18,21,24,27,30,33,36-dodecaoxanonatriacontan-39-oate (265c) (285 mg, 42%). 1H NMR (400 Hz, CDCl3): δ 6.62 (s, 1H), 6.51 (s, 2H), 4.52 (s, 4H), 3.72 (t, J=6.4 Hz, 2H), 3.65 (s, 3H), 3.61 (m, 48H), 2.94 (s, 2H), 2.63 (s, 1H), 2.57 (t, J=6.4 Hz, 2H); MS (m/z): found 790.4 (M+Na)+.
