合成路线1
该中间体在本合成路线中的序号：(XXII)In an alternative process, the chiral morpholino alcohol (XIII) was activated as the sulfonate ester (XX) employing benzenesulfonyl chloride under phase-transfer conditions. Condensation of the alkyl sulfonate (XX) with 4-(tert-butoxycarbonylamino)-4-phenylpiperidine (XXI) afforded the N-substituted piperidine (XXII). The Boc protecting group of (XXII) was then removed by means of a methanolic solution of HCl, yielding the primary amine (XXIII). Alternatively, amine (XXIII) was synthesized by condensation of sulfonate (XX) with 4-amino-4-phenylpiperidine (XXIV) (obtained by catalytic hydrogenolysis of the N-benzyl piperidine (XVII)). Aminopiperidine (XXIII) was finally converted to the title urea by reaction with phosgene, followed by condensation with dimethylamine.
