Procedure

To a solution of 100 mg of (S)-1-[(2R,4R,5R)-4-(4-methoxy-phenyl)-5-[4-(3-methoxy-propyl)-3,4-dihydro-2H-benzo[1,4]oxazin-6-ylmethoxy]-1-(toluene-4-sulfonyl)-piperidin-2-yl]-propan-2-ol (diastereomer 2) (from example 34b) in 10 ml tetrahydrofuran are added 34 mg of potassium hydride and 0.14 ml of N,N-dimethylcarbamoyl chloride at room temperature. The reaction mixture is stirred for one additional hour, diluted with water and extracted with tert-butyl methyl ether. The combined organic phases are dried and concentrated under reduced pressure to afford the crude title compound. The residue is purified by flash chromatography (SiO2 60 F) to afford the title compound as a yellow oil. Rf=0.41 (EtOAc-heptane 2:1); Rt=5.47.
