Reaction Steps

A mixture of 3.58 g of benzyl [4-(3-methoxypyridin-4-yl)-2-(propan-2-yloxy)phenyl]carbamate and 1.14 ml of methyl iodide in 107 ml of acetone is heated at 50° C. (bath) for 1 h. 568 μl of methyl iodide are added and the heating is continued at 50° C. for 30 minutes. The mixture is then concentrated under vacuum, so as to give 4.57 g of 4-[4-{[(benzyloxy)carbonyl]amino}-3-(propan-2-yloxy)phenyl]-3-methoxy-1-methylpyridinium iodide in the form of a yellow solid.
