The reactions were each heated to 12O0C under microwave irradiation for 15 minutes, then cooled to r.t., combined and poured into methanolic ammonia (10OmL of a 7M solution, 0.7 mol) and stirred at r.t. overnight. The mixture was concentrated in vacuo, and the residue partitioned between water (200 mL), 2M HCl (50 mL) and then hexane and ether.

In dichloromethane; at 20℃; EXAMPLE 1. PREPARATION OF 1- (3-BENZYLOXY) PHENYLTHIOUREA (Compound 1); 1. I 02N X 1. 2. 1. TCD ., base >, I Compound 1 [0114] 3-Nitrophenol (X) is converted to ether (Y) by sequential treatment with sodium hydride and benzylbromide. Reduction of the aniline with tin chloride provides aniline (Z). In certain circumstances the reduction may be accomplished using a hydrogen/Pd catalyst system when the substituent on the aryl group does not include an aryl group. [0115] The final product, Compound 1 is obtained by treatment of Z with thiocarbonyl di- imidazole followed by ammonia. 3-Benzyloxyaniline (5 g, 25 mmol) is added dropwise over a one minute period to 4.94 g (27.6 mmol) thiocabonyl di-imidazole in methylene chloride (150 ml). The resulting mixture is stirred at room temperature overnight. An additional 400 mg thiocarbonyl di- imidazole (TCDI) is added and the reaction is continued for 2 hours more. The reaction is diluted with hexane and filtered through silica. Concentration provides 5.1 g of the desired 3- benzyloxyphenyl isothiocyanate. [0116] A portion of this isothiocyanate (50 mg, 0.21 mmol) in 1 ml methylene chloride is mixed with 0.5 ml of 2 M ammonia in methanol. After 30 minutes the reaction is concentrated to provide Compound 1 in quantitative yield. [0117] Alternatively thiocarbonyl di-imidazole (1.1 mmol, 196 mg) is added to a solution of 3-benzyloxyaniline (1 mmol, 199 mg) in dichloromethane (5 mL). The reaction is stirred at room temperature until the aniline is consumed, about 1 hour. A solution of methanolic ammonia (2 M, 2 mL) is added and the stirring continued for 2 hours. Solvent is evaporated and the residue purified by chromatography on silica gel to give 150 mg of (3-benzyloxyphenyl) thiourea.

76% 0.618 g (3.47 mmol) N,N'-thiocarbonyldiimidazole was dissolved in 20 mL acetonitrile, and 0.500 g (3.47 mmol) isoquinoline-3-amine in the form of a suspension in 15 mL acetonitrile was added dropwise in portions. The clear orange solution which formed was stirred for 12 hr, whereupon a reddish precipitate formed. The intermediate product was directly reacted, without workup, with 0.535 g (6.940 mmol) ammonium acetate for 25 min at 85° C. in a CEM microwave (100 watts). The solvent was removed under vacuum. The residue was stirred in water, and the resulting precipitate was suctioned off and washed with water. For further purification the solid was taken up in 5 mL acetonitrile and combined with 50 mL diisopropyl ether. The precipitate was filtered again and dried in a vacuum drying oven at 40° C., resulting in the isolation of 0.540 g (2.647 mmol, 76percent) purified N-isoquinolin-3-yl-thiourea.ESI-MS [M+H+]=204.15 Calculated for C10H9N3S=203.27
