Product 1

HCID 69486555(3R,4R)-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-3-[1-(2-methoxy-ethyl)-1,2,3,4-tetrahydro-quinolin-7-ylmethoxy]-piperidine-1-carboxylic acid tert-butyl ester

Procedure

In analogy to the procedure described in example 14(a), the (3R,4R)-3-[1-(2-methanesulfonyloxy-ethyl)-1,2,3,4-tetrahydro-quinolin-7-ylmethoxy]-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-piperidine-1-carboxylic acid tert-butyl ester [example 9(a)] was treated with methanol/sodium hydride to yield the (3R,4R)-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-3-[1-(2-methoxy-ethyl)-1,2,3,4-tetrahydro-quinolin-7-ylmethoxy]-piperidine-1-carboxylic acid tert-butyl ester as a light yellow oil; MS: 675 (M+H)+.
