The title compound of Example 102 (46 mg, 0.11 mmol), Cs2CO3 (150 mg, 0.46 mmol), KI (10 mg, 0.06 mmol) and oxetan-3-yl 4-methylbenzenesulfonate (30 mg, 0.13 mmol) in DMF (0.9 mL) were microwaved at 130° C. for 2 h. Additional oxetan-3-yl 4-methylbenzenesulfonate (65 mg, 0.29 mmol) and Cs2CO3 (126 mg, 0.39 mmol) were added and microwave resumed at 130° C. for 2 h more. The mixture was purified by silica gel chromatography (EA) to give the title compound (20 mg, 0.04 mmol) as cream solids in 38% yield. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.03 (s, 3H) 2.98 (s, 3H) 3.50 (s, 3H) 4.41 (t, J=6.82 Hz, 2H) 4.58 (t, J=6.95 Hz, 2H) 5.30 (quin, J=7.01 Hz, 1H) 6.83 (d, J=8.84 Hz, 1H) 7.06-7.20 (m, 1H) 7.22-7.35 (m, 2H) 7.39 (d, J=2.53 Hz, 1H) 7.43-7.57 (m, 1H) 7.60 (s, 1H) 7.83 (d, J=2.27 Hz, 1H).
