Participants

Reaction Steps

Sodium cyanoborohydride (0.19 g) was added portionwise to a suspension of 6-(1,2,3,4-tetrahydroquinolin-6-yl)-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one (0.74 g), 36% aqueous formaldehyde (0.34 ml), acetic acid (1 ml) and methanol (3 ml) at room temperature. After stirring for 0.5 hours at the same temperature, the resultant precipitates were collected by filtration, washed with methanol, dried, and recrystallized from 70% aqueous ethanol to give 0.66 g of 6-(1-methyl-1,2,3,4-tetrahydroquinolin-6-yl)-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one.
