The reaction of lumichrome ( 2 ) with alkyl (or allyl)amines such as n ‐butylamine, n ‐hexylamine and allylamine gave 2,3‐disubstituted 6,7‐dimethylquinoxalines 4a‐d, 5a‐d, 6a‐d, 7a‐d and 8a‐d . Similar reaction of 2‐thiolumichrome ( 3 ) with alkyl (or allyl)amines gave 2,3‐disubstituted 6,7‐dimethylquinoxalines 6a‐c, 9a‐c and 10a‐c , 2‐alkyl (or allyl)amino‐6,7‐dimethyl‐3,4‐dihydrobenzo[ g ]pteridine‐4‐ones 11a‐c and 2,4‐dialkyl (or allyl)amino‐6,7‐dimethylbenzo[ g ]pteridines 12a‐c .
