Participants

Reaction Steps

Methyl iodide (0.728 mL, 11.7 mmol) was added to (4-nitro-benzyl)-[(2R)-tetrahydro-furan-2-ylmethyl]-amine Compound 40b (1.84 g, 7.80 mmol) and potassium carbonate (3.23 g, 23.4 mmol) in DMF (30 mL). After 4 hrs, the reaction is was diluted with water and extracted with ethyl ether. The combined extracts are were washed with water, dried over MgSO4, and evaporated to prepare 1.43 g of methyl-(4-nitro-benzyl)-[(2R)-tetrahydro-furan-2-ylmethyl]-amine Compound 150a. Using the procedure of Example 40, Compound 150a was used in place of (4-nitro-benzyl)-[(2R)-tetrahydro-furan-2-ylmethyl]-amine Compound 40b and carried forward to provide 4-({methyl-[(2R)-tetrahydro-furan-2-ylmethyl]-amino}-methyl)-phenylamine Compound 150b. Using the procedure of Example 1, 5-(5-chloro-2-methoxy-phenyl)-4-oxo-4,5-dihydro-3H-1-thia-3,5, 6,8-tetraaza-acenaphthylene-2-carboxylic acid Compound 147c was used in place of Compound 1 and Compound 150b was used in place of 4-piperidin-1-ylmethyl-phenylamine Compound 1k to give Compound 75. MS 579, 581 (MH+).
