Procedure

In analogy to the procedure described in example 1) (h)-(l), (R)-3-[(3S,4R,5R)-4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-5-(4-methoxy-naphthalen-2-ylmethoxy)-piperidin-3-ylmethoxy]-propane-1,2-diol was treated with di-tert-butyl-dicarbonate in dioxane/water in the presence of sodium hydrogencarbonate to yield the (3S,4R,5R))-3-[(2R)-2,3-dihydroxy-propoxymethyl]-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-5-(4-methoxy-naphthalen-2-ylmethoxy)-piperidine-1-carboxylic acid tert-butyl ester. Subsequent mono-tosylation of the aforementioned diol by toluene-4-sulfochloride in pyridine led to the (3S,4R,5R)-3-[(2S)-2-hydroxy-3-(toluene-4-sulfonyloxy)-propoxymethyl]-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-5-(4-methoxy-naphthalen-2-ylmethoxy)-piperidine-1-carboxylic acid tert-butyl ester which after treatment with NaOH in DMSO yielded (3R,4R,5S)-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-3-(4-methoxy-naphthalen-2-ylmethoxy)-5-[(2R)-oxiranylmethoxymethyl]-piperidine-1-carboxylic acid tert-butyl ester. Further reaction of the epoxide with sodium methylate in a mixture of N,N-dimethylformamide and methanol gave the (3S,4R,5R)-3-[(2R)-2-hydroxy-3-methoxy-propoxymethyl]-4-{4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl}-5-(4-methoxy-naphthalen-2-ylmethoxy)-piperidine-1-carboxylic acid tert-butyl ester which was finally deprotected by treatment with hydrochloric acid in methanol to yield the (R)-1-methoxy-3-[(3S,4R,5R)-4-[4-[3-(2-methoxy-benzyloxy)-propoxy]-phenyl]-5-(4-methoxy-naphthalen-2-ylmethoxy)-piperidin-3-ylmethoxy]-propan-2-ol as a colorless foam; MS: 660 (M+H)+.
