Procedure

0.15 g of the compound of Example 149 was suspended in 5 ml of THF, 0.2 ml of triethylamine and a solution of 35 mg of methanesulfonyl chloride in 2 ml of THF were sequentially added thereto under ice cooling, and the mixture was stirred at room temperature for 3 hours. The reaction solution was concentrated, mixed with water, and extracted with EtOAc. The obtained organic layer was washed with brine, and dried over anhydrous sodium sulfate. The solvent was concentrated under reduced pressure, and the thus-obtained residue was recrystallized from EtOAc-hexane mixed solvent to obtain 0.12 g of N-[5-(4-cyclohexylpiperazin-1-yl)-4-(4-fluorophenyl)thiazol-2-yl]-4-(methanesulfonylaminomethyl)benzamide. The obtained compound was suspended in 5 ml of EtOAc, 0.2 ml of 1M HCl.EtOAc solution was added under ice cooling, and the mixture was stirred overnight. The thus-precipitated solid was filtered and dried to obtain 111 mg of N-[5-(4-cyclohexylpiperazin-1-yl)-4-(4-fluorophenyl)thiazol-2-yl]-4-(methanesulfonylaminomethyl)benzamide hydrochloride.
