With sodium hydroxide; ammonium chloride; In ethanol; chloroform; | 2. 2-Amino-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine 5-Acetyl-2-amino-4,5,6,7-tetrahydrothiazolo-[5,4-c]pyridine (110 mg, 0.51 mmol) was dissolved in ethanol (1 ml) and treated with sodium hydroxide (15.4 mg, 0.38 mmol) in ethanol (1 ml). The solution was heated to 100 for 16 hours, then treated with additional sodium hydroxide (25.6 mg, 0.64 mmol) and heated to reflux for an additional 16 hours. Solid ammonium chloride was added, and the mixture was filtered and concentrated in vacuo. The residue was dissolved in chloroform, dried over sodium sulfate and solvent was removed, leaving the title product (67.4 mg, 0.43 mmol, 84% yield) as a yellow solid, which was used without further purification. |

91% | With formaldehyd; acetic acid; In methanol; | 6. 2-Amino-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine A solution of 2-amino-4-(2-aminoethyl)thiazole (1.57 g, 11.0 mmol) in methanol (120 ml) was treated with acetic acid (0.15 ml, 2.6 mmol) and formaldehyde (0.89 ml of a 37% aqueous solution, 11 mmol). After ten minutes, the reaction mixture was concentrated in vacuo and subjected to column chromatography (eluant: 95:4:1 chloroform:methanol:concentrated ammonium hydroxide). The product was obtained as a white solid, m.p. 169-173 (1.547 g, 10.0 mmol, 91% yield). 1 H NMR (DMSO-d6): 6.64 (s, 2H), 3.59 (s, 2H), 2.87 (t, J=6 Hz, 2H), 2.33 (bt, 2H). |

85% | In ethanol; | EXAMPLE 9 2-Amino-5-(N-cyano-N'-methyl-amidino)-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine (n=0, R1 =R2 =H, R3 =CH3, X=NR8, R8 =CN)-FCE 22952 To a solution of 3.1 g (20 mmol) of <strong>[97817-23-7]2-amino-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine</strong> in 40 ml of absolute ethanol, 4.09 (28 mmol) of N-cyano-S,S-dimethyl cyanodithioiminocarbonate (IV: X"=NR8, R8 =CN) was added at room temperature. After standing for 30 hours, the reaction mixture was filtered to afford 2-amino-5-(methylthio-N-cyano-iminomethyl)-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine (V: R1 =R2 =H, n=0, X"=R8, R8 =CN), m.p. 152-155 C., in 85% yield. 4.33 g (17 mmol) of the compound V thus prepared was dissolved in 17 ml of absolute ethanol and treated at room temperature with a 33% solution of methylamine in 55 ml of ethanol. |

The reaction mixture was allowed to stir for 3 h at ambient temperature. The reaction mixture was diluted with water and the solid was filtered through silica gel, washed with water (2*50 mL) to afford the desired product. The filtrate was concentrated, diluted with waterand extracted with ethyl acetat. The organic layer was dried over magnesium sulfate and concentrated to afford 11.6 g desired product. 1H NMR (400 MHz, DMSO-d6): delta 1.41 (s, 9H), 2.43 (t, 2H), 3.56 (t, 2H), 4.28 (s, 2H), 6.80 (s, 2H) |
