In analogy to the procedure described in example 8(b), the (3R,4R)-3-[1-(3-hydroxy-propoyl)-1,2,3,4-tetrahydro-quinolin-7-ylmethoxy]-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-piperidine-1-carboxylic acid tert-butyl ester [example 4(a)] was treated with methanesulfonyl chloride to yield the (3R,4R)-3-[1-(3-methanesulfonyloxy-propyl)-1,2,3,4-tetrahydro-quinolin-7-ylmethoxy]-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-piperidine-1-carboxylic acid tert-butyl ester, which was directly used in the next step without further characterization.
