Reaction Steps
Following the Example 356, 1-(2-methyl-1-(tritylamino)propan-2-yl)thiourea was reacted with 4,8-dibromo-3,4-dihydro-2Hbenzo[b]oxepin-5-one in ethanol under reflux for 18 hours to give N2-(8-bromo-4,5-dihydrothiazolo[4,5-d]benzo[b]oxepin-2-yl)-2-methylpropane-1,2-diamine hydrobromide. Yield 68%. MS (ESI+): 368.0
