Reaction Steps

A solution of 5-(2-butenyloxy)-3,3,8-trimethyl-3,4-dihydrocarbostyril (1.9 g, 7.3 mmol) in N,N-dimethylaniline (5 ml) was stirred at 210° C. for 7 hours in the stream of argon gas. After spontaneous cooling, the reaction mixture was diluted with hexane, and the precipitated crystals were collected by filtration. The obtained crude crystals were recrystallized from ethyl acetate-hexane to obtain 1.7 g of the title compound as colorless needles (89.3%).
