Procedure

To a solution of 0.469 g (1.484 mmol) of the product of Example 52 dissolved in 10 mL of DMF was added 0.614 g (4.452 mmol) of potassium carbonate followed by 0.092 mL (1.484 mmol) of iodomethane and the resulting mixture was stirred at room temperature for 3 h. The reaction mixture was then diluted with ether and washed with water. The organics were dried over Na2SO4, filtered and concentrated in vacuo to provide 0.446 g (91%) of the N-methyl amine as a colorless oil. Electrospray Mass Spec: 330.9 (M+H)+.
