To a suspension of CDI (973 mg, 6.0To a suspension of CDI (973 mg, 6.00 mmol) in dry DCM (10.0 mL) under N2 was added Intermediate A1 (1.38 g, 6.00 mmol) as a solid, in four equal portions, over 10 min and the resulting solution maintained at RT for 16 hr. An aliquot of this solution (247 muL, 0.148 mmol) was added to a suspension of Intermediate J3 (50 mg, 0.16 mmol) in dry DCM (5.0 mL) and the reaction mixture kept at RT for 5 hr. The resulting suspension was diluted with DCM (5.0 mL) and the solid was collected by filtration and then suspended in water (5.0 mL) and sonicated for 3 min. The solid was collected by filtration, washed with water (2¡Á2.5 mL) and dried in vacuo at 45 C. for 16 hr to afford the title compound, Example 21, as a white solid (70 mg, 74%); Rt 4.67 min (Method 1 basic); m/z 579 (M+H)+ (ES+); 1H NMR (400 MHz, DMSO-d6) delta: 1.27 (9H, s), 2.39 (3H, s), 2.72 (3H, d), 5.31 (2H, s), 6.35 (1H, s), 7.08 (1H, dd), 7.20 (1H, d), 7.36 (2H, m), 7.43-7.45 (3H, overlapping m), 7.60 (1H, dd), 7.64 (1H, d), 8.14 (1H, br s), 8.19 (1H, d), 8.27 (1H, dd), 8.58 (1H, br s), 8.89 (1H, br s), 8.92 (1H, dd), 9.33 (1H, br s).0 mmol) in dry DCM (10.0 mL) under N2 was added Intermediate A1 (1.38 g, 6.00 mmol) as a solid, in four equal portions, over 10 min and the resulting solution maintained at RT for 16 hr.
