Reaction Steps

To a solution of 5,7-Dimethoxy-indan-1-one (8.7 g, 45.26 mmol) in the methanol (80 ml) was added n-butylnitrite (6.13 ml, 49.78 mmol) followed by concentrated HCl (4.4 ml). The solution was stirred at 40° C. for one hour during which time a precipitate was formed. The precipitate was collected and dried to yield product as a yellow solid (10 g, 99%). LC-MS: m/e 222 (MH+).
