Abstract
C20H22ClNO5, orthorhombic, P212121 (no. 19), a = 5.001(1) Å, b = 13.085(3) Å, c = 29.765(6) Å, V = 1947.8 Å, Z = 4, Rgt(F) = 0.0783, wRref(F ) = 0.1758, T = 293 K. Source of material The title compound was obtained from the reaction of p-chlorophenylacetic acid, thionyl chloride and (R)-methyl 2-amino-3(3,4-dimethoxyphenyl)propanoate hydrochloride as described in literature [1] and recrystallized from CHCl3-methanol to give crystals suitable for single-crystal X-ray diffraction. Experimental details In the crystal, H atoms were positioned geometrically with C–H = 0.93, 0.97 and 0.98 Å for aromatic, and methyl, respectively, and constrained to ride on their parent atoms, with Uiso(H) = 1.2 (or 1.5 for methyl groups) times Ueq(C).
