Participants

Reaction Steps

A solution of 4-{3-[5-(cyclopropyl-methyl-amino)-8,8-dimethyl-5,6,7,8-tetrahydro-naphthalen-2-yl]-ureido}-benzoic acid methyl ester (Intermediate 59, 0.045 g, 0.106 mmol) in methanol (2 mL) and tetrahydrofuran (3 mL) was treated with a 2M solution of sodium hydroxide (1 mL, 2 mmol) and the resulting reaction mixture was stirred at ambient temperature overnight. The reaction mixture was neutralized with 5% aqueous hydrochloric acid and extracted with ethyl acetate. The organic phase was washed with water and brine, and dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford a solid that was recrystallized from hot acetonitrile to afford the title product as a white solid (0.012 g, 28%).
