(1S,3S,4S)-tert-Butyl N-[1-benzyl-3-hydr­oxy-5-phenyl-4-(picolinamido)pent­yl]carbamate

The title compound, C(29)H(35)N(3)O(4), was obtained by the reaction of (2S,4S,5S)-tert-butyl N-(4-amino-1-benzyl-3-hydr­oxy-5-phenyl­pent­yl)carbamate and picolinic acid using oxalyl chloride as a chlorinating reagent to activate the carboxyl group. In the crystal structure there are two mol­ecules in the asymmetric unit, which are aligned edge-to-face. In one mol­ecule, the pyridyl ring forms a dihedral angle of 22.0 (1)° with the phenyl ring of the terminal benzyl group and 14.3 (1)° with the other phenyl ring; in the other mol­ecule, the corresponding angles are 12.1 (1) and 10.6 (1)°, respectively. The packing is stabilized by inter­molecular hydrogen bonds and C—H⋯π inter­actions.
