The procedure used for the preparation of Example 1 was used to prepare the title compound from 5-amino-7-methoxy-2,3-dihydroimidazo[1,2-c]quinazolin-8-ol bistrifluoroacetate salt (Intermediate A) and 4-[(3-chloropropyl)sulfonyl]morpholine (Intermediate E). High vacuum drying gave the title compound (100%): 1H NMR (DMSO-d6+2 drops TFA-d) δ: 2.17-2.22 (2H, m), 3.14-3.17 (4H, m), 3.22-3.27 (2H, m), 3.61-64 (4H, m), 3.83 (3H, s), 4.16-4.20 (2H, m), 4.28-4.35 (4H, m), 7.30 (1H, d), 7.89 (1H, d).
