RESUMO
In the crystal structure of the title osthol derivative, C(18)H(23)NO(4), mol-ecules are linked by N-Hâ¯O hydrogen bonds into an infinite chain running parallel to the c axis. The CH(3)CH(2)- atoms of the propionamide group are disordered over two sets of sites with refined occupancies of 0.689â (12) and 0.311â (12).
