Reaction Steps

A mixture of 4-(benzyloxy)-2-(1-oxido-2,3-dihydro-1,4-benzothiazepin-4 (5H)-yl)quinazoline-6-carboxylic acid (170 mg, 0.37 mmol) and oxetane-3,3-diyldimethanamine (128 mg, 1.11 mmol) was heated at 170° C. for 30 minutes. Then the reaction mixture was cooled to room temperature and purified by preparative HPLC to afford 4-({[3-(Aminomethyl)oxetan-3-yl]methyl}amino)-2-(1-oxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)quinazoline-6-carboxylic acid, MS obsd.
