Condensation of L-alaninol (I) with benzaldehyde produced imine (II), which was further reduced to the N-benzyl amine (III) by means of NaBH4. Subsequent acylation of N-benzyl alaninol (III) with chloroacetyl chloride (IV) provided the chloroacetamide (V). This was subjected to intramolecular cyclization in the presence of NaH to afford morpholinone (VI). Lactam (VI) reduction employing LiAlH4 furnished the substituted morpholine (VII). The N-benzyl group of (VII) was then removed by hydrogenation in the presence of Pd/C, yielding (S)-3-methylmorpholine (VIII).
