Procedure

A room temperature mixture of Example 29A (39.4 mg, 0.17 mmol), resin-bound dicyclohexylcarbodiimide (225.0 mg, 1.83 mmol/g), and dimethylaminopyridine (60.0 mg, 4.95 mmol) was treated with a solution of Example 28A (40 mg, 0.11 mmol) in a 1:1 mixture of 1,2-dichloroethane and 2-methyl-2-propanol (3 mL), and agitated overnight on an Argonaut Technologies Quest 210. The mixture was treated with resin bound p-TsOH (990 mg, 1.44 mmol/g), agitated for 1 hour, decanted, and washed with dichloromethane. The combined extracts were concentrated and purified by HPLC using 0.1% TFA in H2O/CH3CN to provide the desired product. MS (APCI(+)) m/e 586 (M+H)+; 1H NMR (500 MHz, DMSO-d6) δ12.50 (s, 1H), 8.66 (d, 1H), 8.57 (t, 1H), 7.96 (d, 2H), 7.95 (dd, 1H), 7.71 (d, 2H), 7.59 (d, 1H), 7.36 (d, 1H), 7.29 (d, 1H), 7.29 (d, 1H), 3.17 (d, 2H), 1.97 (s, 3H), 1.58 (m, 12H).
