Procedure:
A mixture of 5.50 g (0.01869 moles) of 3-(2-quinazolinylmethoxy)benzoic acid methyl ester, 30.1 ml (0.0301 moles) of 1N sodium hydroxide and 22 ml of tetrahydrofuran is heated at reflux for 50 minutes. The mixture is allowed to come to room temperature and evaporated in vacuo giving a solid residue. After the addition of water and filtration through Celite the filtrate is acidified with 2.4M hydrochloric acid. The resulting precipitate is filtered, washed with water until the washings are pH~6. The precipitate is dried overnight in a vacuum desiccator and azeotroped with toluene on a rotoevaporator. Drying in vacuo gives the title compound, 4.75 g colorless solid, m.p. 221°-224° C.; IR (KBr) 1695, 1576, 1285, 1220 cm-1 ; NMR (DMOS-d6) 9.73 (s, 1H), 7.34-8.22 (8H, aromatic) 5.56 (2H, s), 3.43 (1H, broad).

Procedure:
To a suspension of sodium hydride (31 mg) in dry dimethylformamide (4.3 ml), there were added successively t-butyl alpha-bromoacetate (835 mg) and (3S,4S)-3-[(1R)-1-t-butyldimethylsilyloxyethyl]-4-[(1R)-1-phenylthiocarbonylethyl]azetidin-2-one (0.42 g), and the resultant mixture was stirred at room temperature for 1 hour under a nitrogen stream. The reaction mixture was diluted with diethyl ether and adjusted to pH 6.86 with a phosphoric acid buffer solution. The aqueous layer was separated from the organic layer and extracted with diethyl ether three times. The extracts were combined with the organic layer, washed three times with brine, dried over sodium sulfate and evaporated. The residue was purified by silica gel chromatography to give (3S,4S)-3-[(1R)-1-t-butyldimethylsilyloxyethyl]-4[(1R)-1-phenylthiocarbonylethyl]-1-(t-butyloxycarbonylmethyl)azetidin-2-one.

A suspension of 2,4-diaminodibenzo[f,h]quinazoline (0.20 g, 0.76 mmol) in 1 N HCl (150 ml) was stirred at reflux for 24 h, then neutralized with NH4OH. The resulting solid was filtered, washed with water and methanol, then suspended in warm methanol (50 ml) for 20 minutes, filtered and dried at 90° C. under reduced pressure. The solid was nearly dissolved in ethanol (100 ml) and 1 N NaOH (˜1.5 ml), filtered, and the filtrate neutralized with acetic acid to give a precipitate which was filtered, washed with ethanol, and dried at 90° C. under reduced pressure. The solid was briefly heated to reflux in pivalic anhydride (4 ml), the solution concentrated in vacuo, and the residue subjected to chromatography on silica gel, eluting with methylene chloride containing a small precentage of ethyl acetate. The pivalamide (not characterized) was hydrolyzed in a solution of methanol (9 ml) and 1 N NaOH (1 ml) at reflux for 1.5 hours. The solution was neutralized with acetic acid, and the precipitate filtered, washed with methanol and dried at 90° C. under reduced pressure to give 2-aminodibenzo[f,h]quinazolin-4-(3H)-one as a beige solid (0.10 g). 1H NMR (DMSO-d6, 200 MHz) δ: 6.69 (br s, 2H, NH2), 7.47-7.84 (m, 4H, Ar), 8.66-8.80 (m, 2H, Ar), 8.96 (dd, J=8, 1 Hz, 1H, Ar), 9.75-9.83 (m, 1H, Ar), 11.26 (br s, 1H, NH).

Procedure:
To 70 ml of pyridine were added 5.24 g of N-hexyl-N-(2-hydroxyethyl)-5-isoquinolinesulfonamide and 3.39 g of p-toluenesulfonyl chloride. The resulting mixture was stirred at 60° C. for 4 hours. Then, the pyridine was removed under reduced pressure to obtain an oily residue. To the residue were added 50 ml of chloroform and 20 ml of an aqueous hydrochloric acid solution having a pH of 2, and the chloroform layer was dried with anhydrous magnesium sulfate. Then, the chloroform was removed under reduced pressure to obtain a residue. The residue thus obtained was subjected to purification by silica gel column chromatography (Wacogel C-200, 100 g; solvent: a 3% methanol solution in chloroform) to obtain 2.60 g of N-hexyl-N-(2-p-toluenesulfonyloxyethyl)-5-isoquinolinesulfonamide.
