Methyl 3-(2-oxobenzothiazolin-3-yl)-propanoate

Abstract

In the title compound, C6H4SC(O)NCH2CH2COOCH3, the bicyclic benzothiazole system is planar within 0.025 Angstrom; the displacements of the carbonyl oxygen and the beta-carbon atom of the methylpropionate substituent from the benzothiazole mean plane are -0.028 (2) and 0.002 (2) Angstrom, respectively. There is a short intermolecular C-H...O contact between the alpha atom of the methyl propionate substituent and the carbonyl oxygen of the oxobenzothiazole group [C...O 3.241 (2) Angstrom]. These contacts link the molecules into infinite chains, running along the b axis of the crystal.
