Participants

Reaction Steps

Methanesulfonic acid (0.04 ml) was added to the mixture of (2,3-dihydro-9-methylthiomethyl-1-benzoxepin-4-carbonyl)guanidine (0.15 g) in methanol (1.5 ml) and the mixture was stirred at ambient temperature for 30 minutes. To the mixture was added diisopropyl ether (3 ml). The isolated crystalline was collected by filtration and recrystallized from a mixture of methanol and diisopropyl ether to give (2,3-dihydro-9-methylthiocarbonyl-1-benzoxepin-4-carbonyl)guanidine methanesulfonate (0.12 g).
