Procedure

O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (1.34 g, 3.56 mmol) was added to a stirred solution of 4a (967 mg, 2.38 mmol) and 4-methylmorpholine (523 μL, 4.75 mmol) in DMF (12 mL). After 5 min, methylamine (3.56 mL of a 2.0 M solution in methanol, 7.13 mmol) was added, and the resulting mixture was allowed to stir at rt. After 3 h, the reaction mixture was partitioned between ethyl acetate and water. The layers were separated, and the organics were washed with water and brine, dried (Na2SO4), filtered and concentrated in vacuo. The crude residue was purified by flash chromatography on silica gel (gradient elution; 0%-85% EtOAc/hexanes as eluent) to afford the title compound 39. m/z (ES) 420 (MH)+; IP=B rating.
