Participants

Reaction Steps

0.167 g (0.000498 mol) of 3-(4-chloromethyl-oxazol-2-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a]thieno[2,3-f][1,4]diazepin-6-one was dissolved in 20 ml of tetrahydrofuran, treated with 1.4 ml (0.0102 mol) of dipropylamine and boiled at reflux for 20 hrs. The solution was completely freed from the solvents, the residue was chromatographed over silica gel with ethyl acetate/ethanol 1:1 as the eluent and recrystallized from diisopropyl ether. There was obtained 0.075 g (38%) of 3-(4-dipropylaminomethyl-oxazol-2-yl)-5-methyl-5,6-dihydro-4H-imidazo[1,5-a]thieno[2,3-f][1,4]diazepin-6-one as white crystals; m.p. 110-111°.
