Reaction Steps

1.9 g of 4-chloroacetyl-9,10-dihydro-4H-thieno[3,4-b][1,5]benzodiazepin-10-one, 3.7 g of piperidine and 15 ml of dioxane are stirred at 80° C. for 1 hour; the resulting mixture is concentrated in vacuo, and the obtained residue is recrystallized from isopropanol/water. 2.0 g of 9,10-dihydro-4-(piperidinoacetyl)-4H-thieno[3,4-b][1,5]benzodiazepin-10-one are thus obtained.
