To a solution of tert-Butoxy-[7-hydroxy-2-methyl-4-(5-methyl-chroman-6-yl)-1-oxo-1,2-dihydro-isoquinolin-3-yl]-acetic acid methyl ester (50 mg, 0.17 mmol) in DMF (1 ml) was added K2CO3 (44.5 mg, 0.322 mmol) and 3-bromopropan-1-ol (40.3 mg, 0.322 mmol) at RT. The resultant mixture was stirred at 70° C. for 3 hr. The reaction mixture was diluted with water and extracted with EA (10 mL*3), dried over sodium sulfate and concentrated to dryness. The mixture was purified by Pre-TLC to afford the title product (30 mg, 55%). LCMS (10-80 AB—2MIN.M): Rt=1.223, purity=93.7%, M+1=510.
