Task: Please create a SMILES based on the description below.
Description: The molecule is a nucleobase analogue that is uracil substituted with a (2-hydroxyethyl)amino group at position 6 and an (E)-(2-oxopropylidene)amino group at position 5; one of 20 modifications to the potent microbial riboflavin-based metabolite antigen 5-(2-oxopropylideneamino)-6-D-ribityl aminouracil (5-OP-RU), an activator of mucosal-associated invariant T (MAIT) cells when presented by the MR1 protein (reported in MED:32123373). It has a role as an epitope. It is a pyrimidone and a nucleobase analogue. It derives from a uracil.
Result: CC(=O)C=Nc1c(NCCO)[nH]c(=O)[nH]c1=O
