Procedure

A stirred mixture of 6-[3-chloro-4-(2,3-epoxypropoxy)phenyl]-4,5-dihydro-3(2H)-pyridazinone (2.91 g, 0.01 mole) methanol (58 ml), and t-butylamine (6.6 ml, 0.06 mole) was heated under reflux for 90 minutes. Evaporation of the solution under reduced pressure gave a glassy solid, 3.79g. The hydrochloride (m.p. 229°-238°C decomposition) was recrystallised from ethanol-ether to give pure 6-[4-(3-t-butylamino-2-hydroxypropoxy)-3-chlorophenyl]-4,5-dihydro-3(2H)-pyridazinone hydrochloride m.p. 234°-238°C (decomposition).
