Participants

Reaction Steps

The title compound was prepared according to the procedure of step 2 in EXAMPLE 57 using an inseparable mixture of 4-(3-iodopropyl)-1,7-dimethyl-1,4-dihydro-9H-pyrazolo[4,3-b]quinolin-9-one and 4-allyl-1,7-dimethyl-1,4-dihydro-9H-pyrazolo[4,3-b]quinolin-9-one (EXAMPLE 59, step 1) and N-ethylmethylamine instead of dimethylamine. The title compound and 4-allyl-1,7-dimethyl-1,4-dihydro-9H-pyrazolo[4,3-b]quinolin-9-one were separable by column chromatography on silica gel eluting with methanol/dichloromethane (1:9).
