Reaction Steps
In a dry box, in a microwave test tube cyclopentanol (600.0 mg, 7.0 mmol) was dissolved in 5 ml of THF. To this solution was added the NaH (273.0 mg, 11.4 mmol) at room temperature and the mixture was stirred for 30 min. N-1,4-dioxaspiro[4.5]dec-8-yl-5-fluoro-8-methylisoquinolin-3-amine (1.8 g, 5.7 mmol) mixed with 15-crown-5 ether (0.13 g, 0.57 mmol) in 15 ml of DMSO was added to above solution. The microwave test tube was capped and moved out from the dry box. The tube was placed into Microwave apparatus and heated to 140° C. for 2 hours. The crude product was purified using a silica gel column to give 263.0 mg (yield 53%). 1H NMR (400 MHz, CHLOROFORM-d) ppm 0.89 (m, 1H), 1.17-1.40 (m, 2H), 1.57-2.02 (m, 10H), 2.05-2.29 (m, 2H), 2.47-2.63 (m, 3H), 3.54-3.78 (m, 1H), 3.90-4.06 (m, 4H), 4.64-5.02 (m, 2H), 6.46-6.77 (m, 1H), 6.79-6.98 (m, 2H), 7.20-7.43 (m, 1H), 8.91 (s, 1H). MS m/z, (APCI); 383.2 ([M+H]+).
