Reaction Steps

To a solution of methyl 12-cyclohexyl-3-(piperidin-3-yloxy)-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (43 mg, 0.091 mmol) in pyridine (0.5 ml) was added dropwise methanesulfonyl chloride (8.5 μl, 0.11 mmol), and the mixture was stirred at 0° C. for 2 hr. Toluene was added to the reaction mixture and the solvent was evaporated under reduced pressure. Hexane and ethyl acetate were added to the obtained residue, and the precipitate was collected by filtration, washed with hexane, and dried in vacuo to give methyl 12-cyclohexyl-3-(1-methanesulfonylpiperidin-3-yloxy)-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (47 mg, yield 94%).
