Reaction Steps
5-Bromo-pyridin-2-ylamine and acetaldehyde were treated under the conditions of Compound 64C to give the intermediate (5-bromo-pyridin-2-yl)-ethyl-amine. This was then reacted with Compound 64A to give the title product. MS m/z 481 (M+1). Step 2. Preparation of (4-{3-[(5-Bromo-pyridin-2-yl)-ethyl-amino]-propylsulfanyl]-5-methoxy-2-methyl-phenoxy}-acetic acid (Compound 68)
