Reaction Steps
(R)-3-(N-Cyclopentyl-N-cyclobutylamino)-8-fluoro-5-methoxy-3,4-dihydro-2H-1-benzopyran (0.53 g, 1.6 mmol) was dissolved in 47% HBr (15 mL) and stirred at 120° C. for 1.5 h. The solution was cooled by adding ice and alkalised by 14M ammonia. Extractive work-up gave 0.5 g of the title compound as a slightly brown oil. IR contained a typical OH-band at 3654 cm-1.
